Cool. Now, what does this imply?
"For almost every purpose, shell functions are preferred over
aliases."
so, how do I write
alias a=b
as a function?
(remember that arguments may contain spaces&c)
a() { b "$@"; }

Way too easy.
how do you declare a variable for storage in the context of the caller?
(using a function)...

The DebugPush & DebugPop routines I used needed to store
the current func's flags in it's context -- I found it very troublesome
inside a function, to store a value into a local variable in the caller.
