I'm not sure if this is a bug, and I don't know if this can be fixed.
I was playing with h3r3tic's Singleton template.
I have overloaded opIndex, and opIndexAssign in a class, and made the class
wrapped the class with singleton (it doesn't have a meaning probably any
function returning class will do the effect).

When getting value, I can skip brackets after function call, like:
foo = bar["something"];
but when setting value (calling opIndexAssign) I am forced to use
brackets around function call, otherwise I get compiler error:
bar()["something"] = foo;

Please take a look at following two testcases:

Sorry, if this issue is a duplicate.
