Hello,
I'm thinking how interesting it would be to add code blocks to Python, so
that arbitrary strings of code can be passed around. It would open up
some interesting possibilities for self-modifying code and generic
programming.
Since Python has already a plethora of ambiguous string
Mark Dickinson added the comment:
I wonder if it would be better to reject Bool data in this context?
It's not uncommon (and quite useful) in NumPy world to compute basic statistics
on arrays of boolean dtype: the sum of such an array gives a count of the
`True`s, and the mean gives the

I couldn't see anything obvious in the devguide so I'm assuming that still
