"An IDE like Eclipse, which relies on static analysis is never going to be good enough for a language as dynamically typed as perl..."
As I said, Perl 5 in my opinion is impossible to be really parsed without run the code. This is way I still wait Perl 6, that is not so dependent of runtime states to define code.
"Perl's multi-threading is still under development..."
I know that! Is also have collaborated to it. The point is that we can’t wait more for a fine multi-threading on Perl. 5 years to develop it is just too much!
