Rather than introducing another casting method, could lexical_cast be
reworked internally to build upon Spirit? That way previous
investments in lexical_cast will just work faster with no changes,
Also, I won't need to stop and think which one I should be using.

The other comment I have is about compilation times with Spirit. Would
a client of construe_cast be pulling in the Spirit headers? If so, my
compiler (VC9/VS2008) would take a lot longer to build the compilation
unit. I don't mind this overhead for source files that are using
Spriit to do non-trivial parsing, but for casts to/from ints and
strings which are very common, I wouldn't want to wait for such long
compiles.
