I would love to see Python seriously consider dropping case and underscore sensitivity in order to speed up developers

How? By making it harder to find all occurrences of an identifier? Case sensitivity is debatable since editors have the option to ignore case during searches, but ignoring underscores isn't something any text editor I've seen has as a default search feature.

And in my world, underscore is more common as a word separator than mixed case. That is, people use 'foo_bar' instead of 'FooBar' or 'fooBar'. (This is more often true in C or Verilog than Python, however.)

Not to mention common idioms like x.y vs x._y where one is a property and the other the actual member.
