[Python-ideas] Settable defaulting to decimal instead of float

[אלעזר]

I think such proposals are special cases of a general theme: a compiler
pragma, similar to "from __future__", to make Python support
domain-specific syntax in the current file. Whether it's decimal literals
or matrix/vector literals etc.

I think it will be nice to make some tool, external to Python, that will
allow defining such "sibling languages" (transpiled into Python) easily and
uniformly.
