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`

A space after the shebang tells the C-shell csh(1) not to interpret the
script as a C-shell script. Other shells, like bash(1) and the POSIX
sh(1) ignore the space but the Bourne shell may not.
