To have a good IDE for Perl 5 is difficult, since Perl 5 has a very complex syntax, especially because Perl 5 depends of runtime states to be really parsed.

I do not believe the later statement to be true. Can you cite credible sources for this assertion?

Better yet, I can give an example. 

$x = foo / bar / - 1;

Is bar a function call, or part of a regexp? It depends on foo's prototype. If foo is an imported symbol, then running code (the exporting module's import function) is required to determine foo's prototype and therefore whether bar is part of a literal or not.

sub foo() { ... }$x = foo() / bar() / -1;
sub foo { ... }$x = foo(m/ bar / - 1);
