perl cannot be parses at all; there are cases where you must run a program to find out whether x is an identifier or a [function] name. Nonsense. A very small category of behavior exists where static parsing of Perl 5 cannot determine whether a given program is valid. That's all. It's possible to write a pathological program which has two valid and working parses, but I've never seen it and it's an intellectual game, not a trap waiting to snare an unwary programmer. (I have no idea what "an identifier or a function name" means, as Perl uses sigils to distinguish between variables and function names.)
