Great job on the library, however I think it could use a little fixing
for the 'as' function.  Passing in a variable of the type in order to
get C++ to know what type to use doesn't sound like the best idea.
Using C++ templates seems to make the most sense to me.

Instead of:
int val = L.as(0, index);
It would be:
int val = L.as<int>(index);

... Just my 2 cents.


I was about to make the same suggestion. And if your original
intention was to write more generic code like :

int val;
val = L.as(val, index);

with a modern compiler you could write :

int val = L.as<typeof(val)>(index);

Not all compiler support the typeof operator yet, but GCC does and
template based limited implementations exist for those that don't.
