feedback on subroutine as both function and method in one
I always like input magic, but there are caveats: What if
the user decides to access your sub as a real function? That is,
xpkg::mproc()... and worse, if the user additionally throws
an hashref at the beginning? Your code wouldn't recognize
Check the following: is it a ref? If not, is it a string with
your package as a name? -&bt; you are called as a class.
Skip the first argument. If not, keep the first. If it is
a ref, is the ref equal to the name of your package? Than the first
argument is $self. If not, you need to keep the first argument.
You see, four possible cases here.
Just a nitbit: no memory allocation is needed in perl.
