The fears about "slow code" are especially odd since ad-hoc 
templates are an important tool to force constant folding and 
many optimizations that requires inlining.

Moreover Go with first its class interface{} values will pay a 
heavy price in dynamic dispatch, something that is optional and 
not really "pay what you use".

Granted code bloat is a real thing and you _might_ have 
instruction cache problems, but the problem only ever show itself 
when the working set of code exceed the instruction cache 
capacity. Ie. a huge executable might not be a good predictor for 
reduced instruction cache efficiency.
