Perl is modeled on natural languages, but that doesn't mean it is one.
 At its core, Perl is a limited, artificial language being explicitly
designed with certain goals.  One of those goals is that it should be
as small as possible given the feature set we want it to support; an
`alias` built-in that essentially duplicates an existing feature goes
against that goal.

I'm not sure what you mean by "context" here.  Context has a very
specific meaning in Perl, representing the type a function's caller is
expecting; this doesn't seem to be what you're talking about here.

This is a couple punctuation symbols short of:
    &kilobytes := &kilobyte;
Or maybe:
    &kilobytes ::= &kilobyte;
I'm not really sure what behavior you have in mind for alias.

(By the way, a simple name like "alias" is ambiguous about argument
order, where an operator isn't.)
