Hello,

AFAIK, using '$' for custom collection types is not yet possible:
oDollar is simply not implemented (correct?). But why do we need it? I
do not understand the logic requiring an opDollar special method to
"desugarise" the '$' operator. For me, '$' simply means length, so I
would be fully happy with the simple rewrite of
coll[$] coll[$-i] coll[i..$]
to
coll[coll.length] coll[coll.length-i] coll[i..coll.length]
The problem is with multi-dimensional indices.
Consider:
a[$-1][$-2];
There are two different values for $.
TDPL has solved that once and for all. The design hasn't been yet
implemented.
