[boost] Re: Review request: enable_if

Jaakko Jarvi wrote code that looks like this:

  template <bool B, class T = void>
  struct disable_if: public enable_if< !B, T> {};

I have a question regarding compile time:
Do you have experience about whether this elegant solution
might have some compile time penalty due to inheritance?
Or is this faster than doubling the code?

IIRC I had such an issue with at least Intel's 7.0 
where I found that removing inheritance brought speed.
And for such a widely used feature this might be important.

You 2 cent appreciated.

Markus
