Hi, Mark. Yes, PEP 3101 is very much under-specified in this area. I tried to avoid the same mistake in PEP 498, although of course that's a different problem area. I don't recall why this particular case broke between 3.2.3 and 3.4.3. I'll try and track it down. I'm sure we were trying to "fix" some other edge condition. FWIW, in 3.4.3 this also fails, as expected: >>> "{ {{ 0} }}".format_map({' {{ 0} }': 'X'}) Can you try it in 3.2.3? I expect it to work, but you never know.

Hi, Mark.

Yes, PEP 3101 is very much under-specified in this area. I tried to avoid the same mistake in PEP 498, although of course that's a different problem area.

I don't recall why this particular case broke between 3.2.3 and 3.4.3. I'll try and track it down. I'm sure we were trying to "fix" some other edge condition.

FWIW, in 3.4.3 this also fails, as expected:
>>> "{ {{ 0} }}".format_map({' {{ 0} }': 'X'})

Can you try it in 3.2.3? I expect it to work, but you never know.
