I was doing some metaprogramming where I wanted to make a slice
of a type:
alias Tbasic = int;
pragma(msg, Tbasic);
alias Tbasica = Tbasic[];
pragma(msg, Tbasica);
//prints int, int[]
And things worked fine until I attempted the same thing on what
happened to be a tuple of 1 element:
alias Ts = AliasSeq!int;
pragma(msg, Ts);
alias Tsa = Ts[];
pragma(msg, Tsa);
//prints (int), (int)
which confused me until I realized that the [] was slicing the
tuple. Note, you can add as many [] as you want since it's
basically a no-op.
pragma(msg, Ts[0][]); //prints int[]
Is there any use for this behavior? It seems like it might be
worth warning like "slicing a tuple is a no-op"
Anyway, figured I'd post here for posterity since I was confused
by it for a while.
