looks_like_number() (Score:2)

You might want to look at the perl API function looks_like_number(), accessible from XS. (see perldoc perlapi.)

  Or from Scalar::Util [perl.org].

    Aristotle, Rafael,
    
    Much appreciated! I was not aware of that function. In this particular case, PPI is designed to be more lenient than Perl (it must be round-trip-safe even on invalid syntax) so we'll stick to our custom tokenizing. That said, I'll probably look deeply at looks_like_number to see if I can find inconsistencies in our tokenizer.
