DIP60: @nogc attribute

Timon has kindly fixed the wrong part I wrote in the DIP60. But 
if we introduce some basic escape analysis required by all 
conformant D compilers, then the @nogc attribute can be applied 
to some functions that define array literals or more (so my 
comment becomes true in some specified cases). Thankfully this is 
something that can be done later, as such improvements just relax 
the strictness of @nogc.
