Re: [ggt-devel] gmtl::makeInverse()

[Ben S. <bs...@ia...>]

You are right. makeInverse() shouldn't need Type2Type. The only reason I 
can think of that it might be there would be to work around a VC7 
compile error. However, I'm pretty sure that's not the case since I'm 
not seeing that in the CVS log.

I give you the green light on removing the Type2Type. When you do 
though, make sure you modify the src argument to pass by const reference 
rather that const value. (I just noticed that error ...)

cheers,
