I finally realized that here was not the best place to bring in the
template specialization. We've had some little-used functions

libmesh_real(x

That was actually the first thing I started coding, so hopefully it
makes some sense. ;-) But DistributedVecto
How about
#ifdef USE_COMPLEX_NUMBERS
// use ::real syntax
#else
#endif
I didn't try this so if that makes no sense sorry.

To expand on that you could even do something like:
template
void auxDoSomething()
{}
template<>
void something >::doSomething()
{
auxDoSomething();
}
That way each of your specializations don't have to have code copied
and pasted into them

Well... I made up a little toy code here... and got several other
people from around the office (who are _very_ knowledgeable in C++
lore) to come try and make it compile... with no luck. It just
doesn't seem to be possible.
I _did_ actually get it to compile with something like this:
template<>

No; I didn't even know that was valid syntax. Are you sure you don't

Have you tried:
template
Real DistributedVector >::min () const {...}

Sure you can... I do it with some of my classes in my code like this
In something.h:

The situation here's a little more complicated.
This works:

Hi developers,
I just downloaded the latest libmesh version and when I compile it in
complex mode, the compiler throws an error from distributed_vector.h:
In member function »Real DistributedVector::min() const [with T =
std::complex]«:
src/numerics/numeric_vector.C:182: instantiated from here
