Anything that uses type deduction?  Most of the time, you do *not* want a  
static array, especially for template functions that use IFTI.

Note that D1 was like this, [1,2,3] was auto-typed to int[3u].  It was a  
constant source of pain that I would not like to revisit.  Especially  
since static arrays are now passed by value.
