Why isn't
"Name " ~ name ~ " could not be found"
implicitly convertible to `string`?
If concatenation is guaranteed to allocate a new array, then it should
be "strongly pure", and the conversion should work. I'm not sure if it
is guaranteed to allocate a new array.
Would
class NameLookupException : Exception
{
this(scope const(char)[] name) @trusted {
super("Name " ~ cast(string)name ~ " could not be found");
}
}
be ok?
Only if you know for sure that you're dealing with a compiler bug here.
As another workaround, you can use std.conv.text:
import std.conv: text;
super(text("Name ", name, " could not be found"));
