I inherited this script, whose code is as follows:
#!/usr/local/bin/perl -w
...
# 'while' starts on line 42
while (($app_key, $app_value) = each %app_file_count) {
delete ($app_file_count{$app_key});e
}
What is the "hanging 'e' on line 43? It is not a subroutine call, and there
is no terminating semi-colon (';'). Yet, when I do a syntax check, I get:
$ perl -c myscript.pl
Unquoted string "e" may clash with future reserved word at my line 44.
Useless use of a constant in void context at my line 43.
myscript.pl syntax OK
I'm confused why this is passing a syntax check. This script runs in
production (without the warning flag).
Thanks in advance!!
Regards,
Jeff
