start your search here errno, errno -> Errno::AnyString - put arbitrary strings in $!

magic, magic -> Variable::Magic - Associate user-defined magic to variables from Perl.

You'll realize that these magic variables look a lot like tied variables. It is not surprising, as tied variables are implemented as a special kind of magic, just like any 'irregular' Perl variable : scalars like $!, $( or $^W, the %ENV and %SIG hashes, the @ISA array, vec() and substr() lvalues, threads::shared variables... They all share the same underlying C API, and this module gives you direct access to it.

t's nearly impossible to manually decode('UTF-8') in each and every place we get $! -

Should have used an abstraction :)  errno(), "@{[errno()]}",  @{[int errno()]}
