More realistic examples would be either of:

1.  Offer users the choice of a longer more self-describing name and a terser 
name.  For example: "function is_member_of|in (...) ...".

2.  Offer users the choice of similar length but different names.  For example: 
"function sum|add(x integer, y integer) returns integer ...".

3.  Make it easier to change your mind on a name while providing backwards 
compatibility for awhile.  For example: "function new_name|old_name (...) ...".

Personally I like the idea of developers not always having to be forced to 
choose among two equally good names, and making a wrapper function would be 
overkill for this feature.
