I think _most_ of the conversation has been fair feedback on the TIP - 
proposing alternatives or enhancements.

Right now the immediate proposal is defined by TIP #405.  I am under the 
impression that the only uncertainty in this TIP is whether [dict map] 
does/should transform dict->dict or dict->list.  The 'tip-405-impl-td' 
branch contains the TIP #405 implementation as specified and nothing else.

Any experimental development on alternatives will happen on a different 
branch.

Agreed.  It's not on the cards for this TIP.  I see no justification for 
changing the behaviour of continue/break in one specific loop (i.e. 
[lmap]); changing their behaviour in all loops would supercede the 
functionality of TIP #405 but would be done as its own TIP (not a change 
to #405).

Break/continue out of nested loops is definitely outside the the scope 
of this TIP.
