How come?  Existing arch names already have a distinctive syntax, so an alias
could be anything else (with the rule that they not intrude on the real
namespace).  It might possibly impact error handling -- a typo could
syntactically look like an alias -- but even this seems very minor, as only
valid aliases would be accepted, and it's very unlikely that anybody would
keep lots of aliases that are a small edit-distance from real names.

The existing patch-NN syntax would look like an alias in such a scheme, but
that's an unproblematic special case I think, and indeed, that feature might
even be able to use the alias mechanism if it were flexible enough (e.g.,
allowed `computational aliases', if only for internal tla use).

[Not that a single-character prefix is all that annoying, I'm just curious
why it would be _necessary_.]
