I just update my Rascal plugin in eclipse(to 0.2.13.201112112047) and now I have a problem with the List.sort method combined with aliases.

Example:

import List;

alias Result1 = tuple[str name, int val, int val2];
alias Result2 = tuple[str name, int val];

bool compResult1(Result1 a, Result1 b) {
    return a.val > b.val;
}
bool compResult2(Result2 a, Result2 b) {
    return a.val > b.val;
}

public void theTest() {
    Result1 r1a = <"r1a", 0, 0 >;
    Result1 r1b = <"r1b", 1, 1 >;

    Result2 r2a = <"r2a", 0 >;
    Result2 r2b = <"r2b", 1 >;

    list[Result1] l1 = [r1a, r1b];
    list[Result2] l2 = [r2a, r2b];

    sort(l1,compResult1);
    sort(l2,compResult2);   
}

rascal>theTest();
std:///List.rsc:141,30: The called signature: compResult1(Result2, Result2),
does not match the declared signature:  compResult1(Result1 a, Result1 b)

It seems to use the first compare method all the time.
