Separated from #40880. This subtle adjustment allows for more accurate type inference in the following kind of cases: ```julia function condition_object_update2(x) cond = x isa Int if cond # `cond` is known to be `Const(true)` within this branch return !cond ? nothing : x # ::Int else return cond ? nothing : 1 # ::Int end end @test Base.infer_return_type(condition_object_update2, (Any,)) == Int ```
