Actually, "carp", used as a verb, meaning complain, has been in use since the 1500s, so is long past the slang stage. However, "croak" is still considered a slang term.	[reply]

Well yes, I can construct mnemonics, German and English being very similar helps. But still I'm confused about the need to have several names for things which are almost similar - i.e. different only in orthogonal dimensions - instead of parametrizing them. Thanks anyway! =) Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply]

I agree that PHPisms like 500 extra, semi-overlapping keywords can be a bad thing but I've always liked Carp's interface. Taking the generalized and parameterized route to extremes is `warn` and `die` becoming replaced with `error($level, $message)` or something. I use Carp's functions enough, including `longmess` and `shortmess` for logs, that I much prefer having specific functions for `ack`ing around and such.	[reply] [d/l] [select]

I'm fine with Huffman* coding keywords (often used = own keyword) and naming functions is indeed difficult ... But I'm still not happy, sorry ! :) Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery} update PS: any need to explain MilliHuffman? ;-)	[reply]

I can only guess why Larry & Co. did it this way, and that guess would be that it was to preserve backwards-compatibility with perl 4, which already had the current interface for warn and die. Did caller exist in perl 4? It kind of makes sense to use a different interface since modules got a lot of changes in 5.0	[reply]

Did caller exist in perl 4? According to http://www.rexswain.com/perl4.html, caller existed in Perl 4, and so did die and warn. Alexander -- Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)	[reply]

From the perl.n manpage of perl 4 patchlevel 36: caller(EXPR) caller Returns the context of the current subroutine call: ($package,$filename,$line) = caller; With EXPR, returns some extra information that the debugger uses to print a stack trace. The value of EXPR indicates how many call frames to go back before the current one. perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'	[reply]
