Review comment:
Reuse: I don't think its's possible 'as is' as I'd like to keep the
default - which gives some troubles if the default itself contains delimiters
(see this impl). Also the replacement in MapFormat is not recursive - that
could be also solved by the caller by calling MapFormat repeatedly, but could
be added.
If you think it's worth moving to MapFormat, I'll try; but I'd like to
retain the `${...}` syntax, which is consistent with Ant, Freemarker or other
interpolation engines.
