Re^2: use strict without typing use strict?

If you wanted to use that all the time, then PERL5OPT is one solution:

$ export PERL5OPT='-Mstrict'
$ perl -e '$x = 1; print qq{$x\n}'
Global symbol "$x" requires explicit package name at -e line 1.
Global symbol "$x" requires explicit package name at -e line 1.
Execution of -e aborted due to compilation errors.

One caveat to keep in the back of your mind if you dabble with `PERL5OPT`: every arbitrary `perl` you may run will see that and (try to) honor it. At `$work` we've got some stuff therein that works fine when run with our separate application copy of a newer version, but woe be unto the person that manages to mungle their `PATH` and instead wind up getting the (long in the tooth) OS' `/usr/bin/perl` instead because there's modules pulled in which have a newer `use 5.xx` constraint and there's much errors and blowing up and the not running (GLEIVEN!`</bad professor frink>`). Probably not an issue WRT just a `PERL5OPT="-Mstrict"` but be aware of that limitation if you start getting fancier. The cake is a lie. The cake is a lie. The cake is a lie.	[reply] [d/l] [select]
