in reply to RFC: Perl regex to validate arithmetic expressions

there's also the option of using Parse::Yapp and validating arithmetic expressions. In general when "discovering" Perl regexes you think they are so powerful that you can use them for a lot of stuff, but if all you have is a hammer, everything looks like a nail.

[LanX]: hm just read an article on heise.de claiming that RPerl is 250 times faster. ... it's that even possible?
[marto]: under certain circumstances perhaps
[RonW]: as I understand it, RPerl "compiles" a subset of Perl to C, so I would expect the final executable to run a lot faster
[RonW]: Is there an English language version of the site?
[LanX]: but Afaik Perl is on average about 10-20 times slower than C
[LanX]: no
