Bug 2720 – Function resolution failure error message is unclear

void foo(int x) { } foo(4.5); Gives the error: dtest.d(11): function dtest.main.foo (int) does not match parameter types (double) I've been using DMD for over 4 years and I still have trouble interpreting the error message. I always think it's the other way around (I expect what is passed to be on the left and the function's signature to be on the right). It also goes against the convention I've seen used elsewhere where parameters are what are defined in the function header and arguments are the values passed to the parameters (so (double) is the list of argument types, not parameter types). Something like: dtest.d(11): Incompatible argument types (double) for function dtest.main.foo (expected (int)) Would be much more helpful. I'll leave it to Stewie to put a keyword on here if he wants. I'm afraid I'll pick the wrong one.

We have a better error message now! testx.d(3): Error: function testx.foo (int x) is not callable using argument typ es (double) testx.d(3): Error: cannot implicitly convert expression (4.5) of type double to int Fixed in D1 and D2 (1.068 & 2.053)
