Build Identifier: I20110613-1736

Trying this in PureXBase:

val a = 5
val (int, int)=>int sum = [a, b | a + b]

results in the following error: "Duplicate variable name 'a'".

Is it a feature? Isn't the parameter supposed to shadow the outer 'val'?

Thanks.


Reproducible: Always

Steps to Reproduce:
PureXBase:

val a = 5
val (int, int)=>int sum = [a, b | a + b]

Xbase does not support variable shadowing for now. It is explicitly validated that you use unique variable names.

See last comment. We don't have concrete plans to change the semantics.
