It's not tested, and sure enough, a glance at the code suggests that `case` and `switch` will evaluate their first argument once for every clause, which is unlikely to be desirable. I say remove it, but if anybody wants to fix and test and re-add `case` (and change it to a square-bracket syntax like `cond`), be my guest.
I don't see why you'd put this in the standard library. I guess it could be useful for when you're maintaining a library and you want to change the name of a function or macro but keep the old name around for a while so people's code doesn't break immediately. But that's a pretty limited purpose.
* Add comp, constantly and complement
relates #1176
* Fix composition order in comp
* comp without parameters returns identity
* Doc edits for comp, complement, constantly
* Test that `(comp)` returns `identity` exactly
* Simplify the `reduce` call in `comp`
* updated version of comp
I have some macros for using pandas and NumPy that expect : to be a keyword instead of an ordinary symbol. These tests will ensure that we don't break this unless we want to.
* added defmacro!
* revert #924#924 had an error and should never have been merged in the first place. (see #903)
* put back import getargspec
Without the `formatargspec` this time.
* Give better error message on failed macro expansion
Better error messages work most of the time. In cases where there are
parameters that aren't valid in Python, error message shown is rather
ugly. But this is better than no error messages at all and such
macros with strange parameter names are rather rare.
* fix flake8 errors
* Minor English improvements
Ignore a new Flake8 whitespace error
Fixes#1157.
The new check is E305. Since we're now using the `--ignore` option, we have to list all the checks that are ignored by default, too.
I decided that ignoring E305 was better than changing the whitespace it was complaining about because, in at least some cases in our current codebase, single blank lines are used to indicate that several top-level definitions are associated with each other. Don't try to ignore the undocumented Flake8 error W504.
Per the straw poll in #908, as an alternative to #1147.
Now you must use `True`, `False`, and `None`, as in Python. Or just assign `true` to `True`, etc.; the old synonyms aren't reserved words anymore.
