The open source world has a chance to change the future of software development. Programmers have flocked to Perl, Python, PHP, Ruby, D and a variety of other open languages because they offer the openness, freedom, and flexibility C gave; moreover, they also the managed advantages of newer languages.
The problem is the languages and the community are fragmented...
I think Parrot is the solution.
Perl is a tool. Python is RAD. Ruby is for large projects.
One byte-code, multiple libraries, and common objects.
And come D's maturity, a Parrot implementation should be targeted for it.
