- Updated the example in the header comment.
The previous example was way old, from back when fields were separated
by commas! Introduced in 20ec0be87 in 2022 according to git blame.
- Renamed a couple internal RExpr classes:
- Not -> NotNot
- And -> AndAnd
- Or -> OrOr
- Ife -> IfElse
This is mainly to leave room for bitwise operators in case we every
want to add them.
- Added isinf, isnan, isint, etc:
- isint(a)
- isfloat(a)
- isfrac(a)
- isinf(a)
- isnan(a)
In theory useful for conditional exprs based on the field's type.
- Accept +-nan as a float literal.
Niche, but seems necessary for completeness. Unfortunately this does
mean a field named nan (or inf) may cause problems...
