 I just have no idea where to put the [] on something like

 Or should I just alias it and make an array of the alias?

  alias f = void function() nothrow pure @nogc @safe;
  f[] arrayName;
 
 Alias is the correct way IMO.

yet

  void function() nothrow pure @nogc @safe [2]arrayName;

is perfectly fine too.

Function pointer array slice?

Ahh, guess that makes sense, I kept trying to put the [] over 
near function()... looks weird as hell though. I really wish you 
could put types in parens, I feel like things like this would 
make way more sense if you could write


 (void function() nothrow pure @nogc @safe)[] arrayName;

Reading it, that makes wayyy more sense to me, to bad I can't 
write this...

attributes are the parts of the type. and the rule is really simple: put 
[] array declaration immediately left of the array name. ;-)

i agree, this is somewhat easier to read. but it requires grammar 
changes, i believe, and dunno what consequences that may have. yet it may 
worth filling a ER.
