alias a function

[JupiterHost.Net]

Hello list,

I was looking into the best way (and for what reasons) you'd create an 
"alais" function.

For example:

If you want foo() and bar() to be able to be used interchangeably would 
 it be best to do:

 sub foo { return "Howdy $_[0]"; }
 sub bar { return foo(@_); }
or do a typeglob:

 sub foo { return "Howdy $_[0]"; }
 *bar = \&foo;
or another way ??

TIA
