"============================ PSEUDONYMS ===================================
"=== PSEUDONYMS by phoe ===

I found that Lisp nicknames, as defined in CLHS, have a few problems that I will count here.

1) They are not changeable without internal side-effects. RENAME-PACKAGE is destructive, as it
kills off any previous names the package.
2) They collide. Nickname GL is used by at least three different Lisp packages.

The solution I provide here is a different approach to nicknames that does not use any of the
original nickname code, as defined in CLHS.

Pseudonyms, in opposition to nicknames, can be defined by the user inside one's code, like
this:
> (defpseudonym \"longpackagename\" \"lpn\")
And removed like this:
> (pmakunbound \"lpn\") ;; OR (pmakunbound \"longpackagename\")

From within the code, one can refer to a pseudonymized package this way:
> $lpn:something
A reader macro will automatically translate it to its normal version of
longpackagename:something. This is usable both within the REPL and within usual code.

All pseudonyms are local to the current package: for instance, pseudonyms defined within
CL-USER are not usable anywhere outside the CL-USER package.

An utility function print-pseudonyms will print all pseudonyms for a given package. If not
supplied a package name as an argument, it will print all pseudonyms for current package (as
shown by the *package* global variable).
