What it boils down to: use warnings as well as -w works, but -w is
considered old fashioned.
The problem with -w is that it can't be turned off. Sometimes a module
has to do something dangerous and having a warning appear is annoying
at best and can cause worry and stress in a programmer. `use
warnings;` can be turned off:
{
no warnings;
# do something dangerous
}
# end of scope restores warnings to the previous value `use` or `no`
Thanks! Didn't know that.
