(jeffa) 3Re: map() abuse or child with a chainsaw

Just for sheer TIMTOWTDI:

@ARGV = @ARGV[2..$#ARGV];

# or for the paran paranoid:
@ARGV = (@ARGV)[(2..$#ARGV)];
[download]

... but i don't like copying the ARGV array back to itself. More readable might be:

my $discard1 = shift;
my $discard2 = shift;
[download]

Out of curiosity, why would one even want to discard the first two arguments like that anyway? Seems like a bad idea in the first place.

Hmmmm ... sounds like time to pull out one of the Getopt modules to me. ;)

Why store the results from the two `shift`'s in variables if the intention is to discard the values? `shift;shift; # Should do it` [download] Everything went worng, just as foreseen.	[reply] [d/l] [select]

I admire you, guys :) Correctly identifying this very needed refactoring by seeing shifting of @ARGV is long beyond my abilities :)) Yes, this utility has home-grown option processing.	[reply]
