Currently associative arrays can't be used much in pure nothrow functions:

void main() pure nothrow {
    int[int] aa;
    aa.rehash;
    auto L = aa.length;
    auto x = aa.get(0, 10);
    auto k = aa.keys;
    auto v = aa.values;
    auto bk = aa.byKey();
    auto bv = aa.byValue();
}


DMD 2.055 gives:

test.d(3): Error: pure function 'main' cannot call impure function 'rehash'
test.d(4): Error: pure function 'main' cannot call impure function 'length'
test.d(5): Error: pure function 'main' cannot call impure function 'get'
test.d(6): Error: pure function 'main' cannot call impure function 'keys'
test.d(7): Error: pure function 'main' cannot call impure function 'values'
test.d(8): Error: pure function 'main' cannot call impure function 'byKey'
test.d(9): Error: pure function 'main' cannot call impure function 'byValue'
test.d(3): Error: aa.rehash is not nothrow
test.d(4): Error: aa.length is not nothrow
test.d(5): Error: aa.get is not nothrow
test.d(6): Error: aa.keys is not nothrow
test.d(7): Error: aa.values is not nothrow
test.d(8): Error: aa.byKey is not nothrow
test.d(9): Error: aa.byValue is not nothrow
test.d(1): Error: function D main 'main' is nothrow yet may throw
