Bug 8270 – Different error messages for missing const in var[] and var.opSlice()

Consider the following code: struct S { void opSlice() { } } void main() { const(S) s; s[]; s.opSlice(); } It results in two error messages from which the second is correct since it comlains about opSlice not being const but s being a const(S). The first one misses this information. Error: function main.S.opSlice () is not callable using argument types () Error: function main.S.opSlice () is not callable using argument types () const This bug does not seem to affect other operators like opIndex or opCall.

Fixed in 2.061, both messages are like #2 now. However it will also get better after pull 1407 is merged (http://d.puremagic.com/issues/show_bug.cgi?id=8270): test.d(12): Error: mutable method test.S.opSlice is not callable using const object test.d(13): Error: mutable method test.S.opSlice is not callable using const object
