           Summary: Cannot slice mixed tuples
           Product: D
           Version: 0.174
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: rejects-valid, spec
          Severity: critical
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: daekharel gmail.com


template Tuple(E ...) { alias E Tuple; }

alias Tuple!(float, float, 3) TP;
alias TP[0..length-1] TQ;

DMD gives following error when compiling the above:

err.d(4): tuple E is used as a type
err.d(4): Error: can only slice tuple types, not void

This doesn't exactly contradict the spec (AFAIK), which is a little vague about
using tuples outside of templates, but it does directly contradict the essay at
http://www.digitalmars.com/d/tuple.html, which in fact uses this as an example.

See also bug 586, which refers to the same problem with indexing tuples.
