SFINAE for unique_ptr

I my attempt to fix https://bugs.kde.org/show_bug.cgi?id=294306 I am now stuck 
at the SFINAE thingy to figure out the return type of most of unique_ptr's 
methods, namely _Pointer::type.

// use SFINAE to determine whether _Del::pointer exists

I have a rough understanding of how this should work like in theory, but does 
kdevelop already have any support for that? I cannot find any match for that 

Right now, unique_ptr<Anything> will always result in return-types of 
unique_ptr<Anything>::pointer which is "correct" but not what we want. Code 
completion doesn't grog it either...

So... help?
