So this works now:
var a1 = "Hell";
var a2 = 1,2;
var a3 = extend a1 with a2 end;
println$ a3;
var a4 = extend a2 with a1 end;
println$ a4;
var a5 = extend 1 with "silly" end;
println$ a5;
var x : extend int * long with double end;
x = 1, 2L, 1.2;
println$ x;
It does NOT handle arrays yet. With some fiddling this is
the "tuple cons" operation already, for both values and types.
So we only need the "unpack" operation, either
hd,tl functions
or
pattern match like ?hd ,, ?tl
where ,, is hd+tail for tuples. Maybe syntax
?hd, ?tl ...
would be nicer but issue here is just to get the operator.
for both values and types.
