missing proxy to automatically cast an sc_bv element to a bool?

Hi all,

I'm using a bit-select of a sc_bv in an expression, something like this:

sc_bv<8> mybits;
...
if (mybits[0].to_bool())
  // do something

Sure this works, but I'm not so happy with this coding style. Therefore I expected some intelligence in the sc_proxy class to resolve the bit to bool conversion, simply because the sc_bv can be seen as an array of bools.

I expected that this would work as well:

sc_bv<8> mybits;
...
if (mybits[0]) // compiler error here
  // do something

Pity... we get the following compiler error:

... error: could not convert ‘sc_dt::sc_proxy<X>::operator[](int) [with X = sc_dt::sc_bv_base](0)’ to ‘bool’

It seems this type of functionality is not (or cannot be) implemented in the sc_proxy?
