( #3333=superdoc: print w/replies, xml ) Need Help??

It seems Tim Bray made a classic benchmarking mistake. He compared dissimilar things and thinks the result is meaningful. On the other hand, it would be very difficult for most observers to have any idea of how Perl and Java regular expressions are really implemented, so I can hardly fault him for this. I likely would have come to the same conclusion despite my knowing both languages.

    [1nickt]: tobyink perl -MTypes::Standard= is_Int -Mstrict -wE 'say 1 if is_Int 1.0'
    [jdporter]: so that I can use the existing expand unix util. Otherwise, I'll probably use Text::Tabs.
    [1nickt]: pryrt I guess I don;t really care if user 42 logs on as 42.0 ... more of an academic question at this point.
    [LanX]: jdporter: open PIPE,'-|' ?
    [LanX]: oh you want the result line by line?
    [jdporter]: ok, LanX, then what?
    [jdporter]: It doesn't have to be line by line. Just "my program" "writes" to the external prog and also/then "reads" from it.
    LanX open (You are not allowed to open to a command that pipes both in and out, but see IPC::Open2, IPC::Open3, and Bidirectional Communication with Another Process in perlipc for alternatives.)
    [jdporter]: IPC::Open2, I guess
    [jdporter]: yes, that
