Haven't read the whole thread, so apologies if I'm missing something, but:

Please let's not invent a reserved word that uses different variable
expansion rules.  The sequence «hash[$key]» should mean the same thing
everywhere.  Instead, we could have a builtin that takes two separate
arguments, as in «foo hash $key» (and «foo hash ''» to unset the element
whose key is the empty string).

Makes sense?

Cheers,

Daniel
