You have a wrong logic. This script will mkdir if it exists.
use

its counterpart 'global' existed, as it could help clarify the intended

'function name

declaration is replaced by 'echo this is the alias'. Unfortunately, you
can't quote the function name in the declaration, so you have to either
use 'function' or say unalias foo first.

Interesting article. One thing not mentioned there is declarations.

Not particularly useful, but you can't replace that with a function (as
