Okay, so you need to do popFrontN(s, n - 1).
Right, silly me :-) I need to read error messages.
I'm too used to arrays which allow you to use that sort of syntax.
Me too.

Hi everyone,
Was hoping someone could help me make sense of this bit of C++ code:
class canvas
{
operator HDC() { return _hdc; }
protected:
canvas(HDC hdc): _hdc(hdc) {}
HDC _hdc;
}
From what I understand, HDC is an alias for HANDLE in Windows. So
they are overloading canvas such
static if ( is(abc U : U[]) )
... aliases U to whatever abc is an array of.
In the case of an associative array, is it possible to retrieve both the
value and key type? (D1)

I am simply unable to imagine how to use this feature that way. Has

Hey!
May be a silly situation but i'm trying to append a search path for

Adding the path to sc.ini won't help because the project' sources

See this:
http://www.digitalmars.com/ctg/ctgLinkSwitches.html#scanlib
You pass switches to the linker via -L, so the switch might be:
dmd -L/SCANLIB
Of course you would have to update the LIB environment variable in
command line, or via a batch file before calling DMD:
set
One more thing:
If your lib files are relative to your current working directory, then
you can just pass them to DMD. E.g. if your lib file is under the
subdir folder of your current working dir you can just use:
dmd main.d subdir\mylibfile.lib
But maybe you knew that already.

bearophile,
You do have a point there, and I actually expected that response.
I would have posted my attempt at implementation, but am unable to
