Does 7 .USD *really* look that much better than USD(7)?  And, really,
how often do you need currency literals?  All my currency values come
from non-literal sources -- databases and XML files, an excel
spreadsheet, etc.  I don't think this objection is particular to
currency either -- for most types this is true.  If you are using them a
lot, you are acquiring them from non-code sources.

Though I suppose Rebol would be a counterexample.  And, in the case of
scripting (a kind of programming, not a kind of programming language :)
it might be a more valid need.  But most of Rebol's interesting data
types aren't syntactically valid in Python anyway.
