Re: local functions

[Bart Schaefer <schaefer@xxxxxxxxxxxxxxxx>]

The current git head has a new utility function
Completion/Base/Utility/_shadow that can be used to simulate local
function names.  You write

   {
     _shadow myfunc
     function myfunc {
       # Do your new thing
     }
     # call myfunc as needed
   } always {
     _unshadow myfunc
   }

If there is already a function named "myfunc" it gets moved aside and
replaced by the new one, and then moved back by _unshadow.  This can
also be used to temporarily replace a builtin.

The functions aren't really local -- they exist in the global scope,
so there's still a chance that something that wants to call the
original one will get the newer one by mistake -- but that's pretty
similar to what happens with local parameters.
