I think it would, and it would likely also require function calls to
loadable functions (at least given the current design whereby encoding
conversions are farmed out to loadable libraries).  I do not especially
want the lexer doing that; it will open all sorts of fun questions
involving what we can lex in an already-failed transaction.

It may well be that these issues are surmountable with some sweat,
but it doesn't sound like an easy patch to me.  And how big is the
use-case, really?
