 Should this work? Currently it doesn't because c's type is deduced as 
 double[3].
 The literal can initialize either double[3] or double[], so the question 
 is only what the default should be when "auto" is used.


double[] is safer and more flexible, so I think that has to be the default. The
double[3] is a (very useful) optimization.

auto c = [2, 3.14, 6.023e22];
=> double[]

double[$] c = [2, 3.14, 6.023e22];
=> double[3]
