in reply to $_[0] fails for file handle?

That is because the <> operator has two functions.    my $line = <$_[0]> ; is the same as my $line = glob "$_[0]" ; while my $line = <$FH> ;
is the same as my $line = readline $FH ;

[LanX]: but but but ... the errors are nicely formatted!
[tye]: 1) The python stack traces show you the names of variables, not the values of variables. Almost never informative.
[LanX]: do you have a py job now?
[tye]: Right now I have errors trying to fetch stuff from graphite. It says 'apps not ready, check startup logs'. I eventually find the startup logs and see 'no apps found'. Looking for fixes to this problem...
[LanX]: no idea ... ask py monks! ;-p
[tye]: it turns out that this can be caused by almost anything going wrong. If you want to know what caused the problem, you have to try to load each app by-hand to see what problems it is having, because none of those will be logged.
[tye]: No, I write more Perl than py at work. But I have to deal with plenty of py things.
[tye]: py monks would just be offended.
[Corion]: ;)
[Corion]: Hi tye btw ;)
