Templating (again)

[zbeekman]

This is a place to discuss templating as a new/additional Fortran language feature, rather than issue #2, which is a more procedural discussion about how to adequately document proposed language features.

I personally think this has been hashed out many times in the past, and that there are some very serious drawbacks to the notion of templating, including combinatorial explosion of generated code, incomprehensible error messages, and hindering compiler optimizations, to name a few. I think there are better alternative approaches to generic programming, but wanted to open this issue since it was brought up by @wadudmiah on #2 and I am certainly open to hearing other peoples opinions, suggestions, concerns etc.
