If this isn't supposed to work for narrow strings, then perhaps a template specialization for the unsupported types that raises a useful error message is the right solution here? -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

To wit, anytime a user gets a cryptic error message buried deep inside a library in response to a simple mistake, you have disempowered them from solving their own problem and derailed their momentum in learning the language. That said, under 2.058 the error message is now: test.d(11): Error: cannot implicitly convert expression (start) of type char[] to ulong Which makes it clear that find(string, string) is returning a slice. I think this specific issue should be closed. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

This behavior appears to be as designed. The compilation problem is caused by
special treatment of the narrow strings by std.array:
http://dlang.org/glossary.html#narrow%20strings
import std.array;
import std.algorithm;
void main()
{
char[] s = narrow.dup;
s.remove(0); // Error: template std.algorithm.move(T)
// does not match any function template declaration
// Error: template std.algorithm.move(T) cannot deduce
// template function from argument types !()(dchar,dchar)
// remove troubles are caused by the special treatment of narrow strings
// front(s) doesn't return a char reference but dchar value instead:
s.front = 'c';// Error: s.front is not an lvalue
}
dchar version works fine:
void main()
{
dchar[] u = unicoded.dup;
u.remove(0);// works fine
u.front = 'c';
}
