The most user-friendly solution would likely be to go BigDecimal
by default and offer either a command-line switch or some pseudo-
require "fastdecimal" to default to Floats instead (although the
latter would need logic for handling files already loaded.) It
would need a toggle in the parser, presumably, presenting a fairly
minor overhead? I would imagine most Ruby programs do not depend
on floating point performance. A configuration option for the
same works too, of course, but not needing a specialized build
is probably a good thing.

If this seems like a reasonable way to go, it should not be too
difficult for someone patch it for you.
