to get the λ character. The difficulty of typing is a red herring. Once
it is a part of the language, every editor targeted at a Python programmer
will provide the means to type λ with fewer than 6 keystrokes (6 is the
number of keystrokes needed to type "lambda" without autocompletion.) The
unfamiliarity is also not an issue. I am yet to meet a Python programer
who knows what the keyword "lambda" is but does not know how the namesake
Greek character looks.
I am +0 on this feature. I would be +1 if λ was not already a valid
This is one of those features that can easily be ignored by someone who
does not need it, but can significantly improve the experience of those who
