Bug 10418 – bad error message: "not a property"

=== struct S { @property void number(int a) { } } void main() { S s; s.number = "10"; } === $ dmd test22 test22.d(7): Error: not a property s.number As you can see, it obviously is a property, but it takes int and I gave it a string. A better message would be Error: not a property s.number(int) or better yet, Error: cannot implicitly convert expression ("10") of type string to int especially since there are no overloads. If there were, I think what would be best is something like: Error: no matching function "number" for arguments (string). Did you mean number(int)? Listing all possible overloads could lead to really spammy messages, but if it ran the spell check algorithm on the type signatures and gave the closest match(s), I think that would be manageable and generally useful, in all cases with overloaded functions.

oops, I meant for the first better one: Not a property: number(string) since that's what it is trying to do, not number(int).

When bug 10103 was fixed, it had been improved at the same time. https://github.com/D-Programming-Language/dmd/pull/2047#discussion_r4298441
