Windows interpreter immediately crashes on this command:
>>> "{[{}]}".format({"{}": 5})

Confirmed on Linux too. This only affects 3.3+, on 2.7/3.2 it returns '5'. |

Here is a patch, which fixes the issue. This brings up rather subtle issues. For example you can have "{[{}]}" but not "{[{]}" as a format string. I wonder if having braces in the field name at all should be an error.

Here's a more comprehensive patch. It follows the PEP by allowing "{" and "}" inside "[]" in the field name.

> I wonder if having braces in the field name at all should be an error. There's some discussion of this in issue #12014; e.g. msg137617. I'm not sure what conclusion was reached. Eric? |

The first patch looks better for me. It is simpler and I do not sure the thing is worth a complication. |
