Does Parrot make it easy to have different versions of a language engine, say Perl, loaded at the same time?
Nope. Modules yes, but perl versions (or any language version) no. I suppose we could, but I'm not sure it'd work as well as you might like, since many of the bugs worked around are as likely to be parrot bugs as language implementation bugs, and it's pretty likely the language implementations will be pretty grubby and not play well with other versions.
Having said that, it's certainly possible, though you'd likely be better off bytecode-compiling the programs or modules to fix in their behaviour and go from there.
