Much to my chagrin I realized this morning that this notation:
while(<FILE>) {
evaluates as:
while(defined($_ = <FILE>)) {
... and NOT as:
while(defined(local $_ = <FILE>)) {
I had a subroutine that was set up to read and parse a file, but it was
trashing the value of $_ out in the main program!
If I use:
foreach (<FILE>) {
... it works perfectly (though slurping the whole file right at the start, I
know).
My question is: why? Seems like such an easy thing to have done.
TIA.
