Yeah, it caused many headaches. Fixed thanks to Kenji, of course (who else?).

I think you should file this as a bug.

That was fixed in 2.064+

Ah, classic Perl. Write once - don't bother to read ever again. :p

Btw one thing I'm not fond of is the format specifiers, in particular:
$` part of input preceding the match.
$' part of input following the match.

I'm reading through http://www.regular-expressions.info, and there's a
feature that's missing from std.regex, quoted:
-
All the characters between the \Q and the \E are interpreted as
literal characters. E.g. \Q*\d+*\E matches the literal text *\d+*. The
\E may be omitted at the end of the reg

It might have been an oversight, but we'll have to wait for (I think
Kenji) to reply since he implement

Sure: version(assert) SList
Here's some improper code that is not checked properly by SList
(meaning no assertions, not even in debug mode):
-
import std.stdio;
import std.container;
void main()
{
auto s1 = SList!string(["a", "b", "d"]);
auto s2 = SList!string(["a", "b", "d"]);
// note the s1[] instead of s

You're likely not loading the function pointers first. Try calling
DerelictGL.reload() first.

Depends on whether the arguments are known at compile-time, and the

Technically no, it changes the reference in the caller, not the actual
object itself. That object is likely still alive until collected if
there are no other references to it.

Well if it's only used in CTFE, I'd imagine a simple struct wrapping
an array and doing "!canFind" when adding elements would do the job,
no?
