I agree, this would allow for a best-effort conversion of various
numerical libraries (e.g. big nums, vectors, etc)
It also provides a good duality when compared to __tostring.

FWIW, luajit supports tonumber on numerical cdata objects (e.g. I can
tonumber() a uint32_t)

Though I wonder, with the addition of integers, do we need a
tofloatingpoint() and tointeger() (where tonumber would be a alias for
the former)
