std.conv.parse of string literals

[bearophile]

This is a small D2 program that uses parse:

import std.conv: parse;
void main() {
    parse!int("111");
    parse!int("111");
}


Gives the error:
std.conv.ConvError: std.conv(1122): Can't convert value `' of type string base 
2 to type int

But a string literal isn't a lvalue. This seems all wrong.

In Bugzilla there are related bugs about strings. Do you think this is worth 
another bugzilla entry?

Bye and thank you,
