Description Nick Treleaven 2022-11-07 12:14:45 UTC 
E.g. this code:

void foo(void delegate(int) dg)
{
    dg();
    //writefln("%s", dg(3));
}

Below due to the backticks it looks like 0 was the argument value passed, not the expected number of arguments.

Error: delegate `dg(int)` is not callable using argument types `()`
       too few arguments, expected `1`, got `0`

Should be:
       too few arguments, expected 1, got 0

PR incoming.
