I can not understand, why this code works:

    char s[2] = ['0', 'A'];
    string ss = to!string(s);
    writeln(parse!uint(ss, 16));

but this can deduces template:

    char s[2] = ['0', 'A'];
    writeln(parse!uint(to!string(s), 16));

What's the reason?

`parse` takes its argument by ref. It pops the characters it
reads from the source. So in your first snippet, ss will be empty
when parse is done with it.

And what is the right way to parse char[2]->int with radix?

In this case you can use to!uint(foo, 16) instead.
