The code compiled and runs successfully:
   void[0][string] hash = [ "text" : [] ];
   writeln(hash);
   assert(hash.length == 0);

Output result is "[]".

Is that a bug?

A static array with a dimension of 0 is allowed, but no space is 
allocated for it. It's useful as the last member of a variable 
length struct, or as the degenerate case of a template expansion.

Judging by compler output, zero size static arrays are removed 
completely, so no surprise that nothing is done.

void[0], OK
void[0][], ERROR
