Builtin scope
Conditional local override of builtin
If a builtin name is conditionally shadowed by a local variable, a name lookup should union the builtin type with the conditionally-defined type:
def _(flag: bool) -> None:
if flag:
abs = 1
chr: int = 1
reveal_type(abs) # revealed: Literal[1] | (def abs[_T](x: SupportsAbs[_T@abs], /) -> _T@abs)
reveal_type(chr) # revealed: Literal[1] | (def chr(i: SupportsIndex, /) -> str)
Conditionally global override of builtin
If a builtin name is conditionally shadowed by a global variable, a name lookup should union the builtin type with the conditionally-defined type:
def flag() -> bool:
return True
if flag():
abs = 1
chr: int = 1
def _():
# TODO: Should ideally be `Unknown | Literal[1] | (def abs(x: SupportsAbs[_T], /) -> _T)`
reveal_type(abs) # revealed: Unknown | Literal[1]
# TODO: Should ideally be `int | (def chr(i: SupportsIndex, /) -> str)`
reveal_type(chr) # revealed: int
