The point is that refusing something you can have now (though
of course it's an open question whether TDNR is something we can "have
now") out of fear that it'll prevent you getting something better
later is speculative and often backfires.
I think we are very far from having TDNR "now". It is really quite
complicated to interleave name resolution with type checking in any
compiler. So far, we have a design, that's all, no implementation.
We also have (several) designs for proper record systems.
If the outcome of this discussion is a clamour for better records
instead of TDNR, then that would certainly make me happy.

Malcolm
