Allowing underscores in string arguments to the Decimal constructor. It could be argued that these are akin to literals, since there is no Decimal literal available (yet).

I'm +1 on this. Partly for consistency (see below)--but also, one of the use cases for Decimal is when you need more precision than float, meaning you'll often have even more digits to separate.

* Allowing underscores in string arguments to int() with base argument 0, float() and complex().

+1, because these are actually defined in terms of literals. For example, under int, "Base 0 means to interpret exactly as a code literal". This isn't actually quite true, because "-2" is not an integer literal but is accepted here--but see float for an example that is rigorously defined, and still defers to literal syntax and semantics. -------------- next part -------------- An HTML attachment was scrubbed...
