you do believe that my $str = "..."; chop $str modifies the lexical

Yes, with *explicit* passing of a lexical, it is easy to understand how it is done; and if the compiler "knows" about chop (as a 'builtin' function), I can understand now how this work for this case. I wonder whether it would also be possible to write a user defined sub which, when called without parameters, acts on $_ even if it was lexically declared. I don't see how this can be done...
