[cam.pm] Compensatory typos

[Roy Chaudhuri]

Hi all,

Sorry to abuse the mailing list by talking about Perl, but I made a 
vaguely entertaining discovery the other day. I was writing a one-liner 
to print out lines from a tab-delimited file which had a last field of 
less than 0. Obviously I wanted to write something like:

perl -ne '@a=split /\t/, $_; print if $a[-1]<0' myfile

but because it was a Friday and my brain was firmly in neutral I managed 
to type this instead:

perl -ne '$a=split /\t/, $_; print if $_[-1]<0' myfile

Weird thing was, one typo cancelled out the other and it still worked. 
Took me a fair amount of trawling through perldoc to work out why.

Anyway, ignore me, back to talking about pubs. Osborne Arms sounds good 
to me.

Roy.
