Useful? I don't think so... but I thought I'd point it out ^^
I think it's a feature that this doesn't work. As for variadic
grouping, named parameters could easily solve this problem, and
have applications for other situations beside variadic
arguments.
I'm not sure how named parameters would solve the original
problem but using a syntax like what I'm suggesting one can do
stuff like
template Log(alias cond, args...; string file = __FILE__, string
mod = __MODULE__)
{
}
which could be called without explicitly having to supply
__FILE__ and __MODULE__, currently you can't write such a CT
logging feature with variadic parameters.
(although another solution would to have __PREVIOUS_FILE__,
__PREVIOUS_MODULE__, etc... that would return the file, module,
line number, etc.. of what called the template or function)
I think using the ';' notation is very concise and natural...
just that forgetting to use it could be very problematic.
