std.regex literal syntax (the \Q…\E escape sequence)

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

Re: Shouldn't SList in std.container hold an owner pointer to verify a range belongs to the list?

Shouldn't SList in std.container hold an owner pointer to verify a range belongs to the list?

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 s2[]!
