    <thetext>Given this exciting function:
function f() { let eval=eval; print(a)}

We get the error

Cannot access uninitialized variable

It appears that triggering this requires using a variable named eval, and also accessing eval in the same scope.

This is very clearly a P0 :D</thetext>

    <thetext>I wish I recalled the context for this, but afaict given current semantics this is correct behavior.</thetext>
