Reassigning Fn

[yhara]

Example

var x = fn(){ 1 }
p x() + 1
x = fn(){ "a" }
p x() + "b"

Result

Error: the argument other' of Int#+' should be Int but got String

Expected

1. Type of x is inferred as Fn0<Object> which is the nearest common supertype of Fn0<Int> and Fn0<String>
2. Therefore x() + 1 is typeerror
