This will not really work for me. This was just an artificial example. In
reality I have generic header which defines the template, another common header
which defines some not very specific specialization and multiple (number changes
as project grows) headers where I define more specific specializations. I can't
"NOT" all the specific conditions in "scalar" level specialization - It's just
not maintainable.

Any other options?

Thank you,
