Perls of taking a vacation...

[Jerry LeVan]

After programming every day for about 25 years I retired a year ago and 
quit programming for a year.

I recently bought a soldering station that displays temp in Centigrade 
so yesterday I saddled up again and ran into the wall with this code 
for a bit...

#!/usr/bin/perl
if ( scalar @ARGV ==0){
    print "ftoc <deg>\n"; exit ;
}
print (5.0/9.0)*($ARGV[0]-32.0), " Centigrade\n" ;
I had to grab the Perl book and found "If it looks like a function it 
is a function".

Y'all ever been bit by this type of misdirection?
