Since as_literal is used quite some time already, I don't see any compelling reason to rename it. I agree as_literal can't be renamed. Now we have to look for a new name? `SIZE(as_???("ab\0c")) == 4`
as_??? returns in constant time. I don't find the name yet. :-)
I'm not sure if this case is important enough to get special as_XXX threatment.
IMHO if you need nulls inside a string, you should use std::string or just a plain array. literal with null is dangerous at least.
\0 is not so important in this case. iterator_range
r = as_literal("million characters which contains no null..."); incurs significant overhead even if you know the string contains no null.
Well, if the performance is the problem, you can always construct the range manually. In this case it could be done in compile time. This is a special case and I don't think, that it needs to be handled on the generic library level. But at the end, as_literal is a part of range library, so it is up to Thorsten to decide. Pavol.
