Nonetheless he is also a co-spec lead of JSR-241, which aims to introduce "Groovy - A New Standard Programming Language for the Java Platform."
"The Groovy Programming Language proposes the standardization of a new programming language for the Java Platform," Monson-Haefel writes in his blog, "one that's on equal footing with the Java programming language."
According to Monson-Haefel Groovy is "an agile, dynamic programming language like Python, Perl and Ruby, but it's designed specifically for the Java Platform and is completely interoperable with conventional Java programs." Groovy isn't a replacement for the Java programming language, he adds, it's a complement to that language. "It fills a niche that is in demand by developers but is currently neglected by the Java Platform."
"Until now," Monson-Haefel continues, "the Java programming language has reigned supreme as the standard programming language for the Java Platform. It has served us well for close to nine years, but it cannot be all things to all people. And it shouldn't. The Java Programming language, like C++ and C#, is a strongly and statically typed programming language. While this type of language, sometimes called a 'conventional' language, is useful for solving many problems, it is not a panacea. Conventional programming languages are very exacting, meaning that you have to dot every 'i' and cross every 't' in order for the program to compile. This orthography of statically defining all the types may result in more predictable code, but it also tends to slow developers down."
His blog continues:
"An alternative to conventional programming languages are agile programming languages like Python, Ruby and Perl among others. These agile languages have long been called 'scripting' languages, but that term is not, IMO, sufficient. Many in IT perceive scripting languages as layman languages that sacrifice technical sophistication for easy of use. This may be true of some scripting languages, but it's certainly not the case with Python, Ruby or Perl. These are dynamic and powerful programming languages that happen to use less syntax to accomplish more.
To be perfectly honest, although I'm listed on the JSR as a co-spec lead, I'm a Johnny-come-lately to the Groovy bandwagon. Groovy already has a grass roots following and all the credit for the development of Groovy goes James Strachan and other contributors to the Groovy open source project. I'm not a language designer, but I understand the power that languages like Python and Ruby offer developers and I believe it is time for the Java Platform to include an agile programming language. It's this personal conviction that led me to initiate and co-develop JSR-241 with James Strachan and Gier Magnusson of Apache. My role as a specification lead is to manage the progression of this JSR through the JCP and author the Groovy Language Specification - two tasks that can be terribly distracting to those doing the really hard work of developing the JSR itself.
