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.
