It occurs to me it's a syntax error everywhere to put two
potentially-calculable terms in a row with nothing between them, e.g.:
```python
a = b c
mylist = [x 6 for x in y if "a" in x]
```
Unless I'm missing something, this makes it relatively easy (from a
syntax perspective; writing a pa

I can't actually think of any other unary operators.

The fundamental point you seem to miss is that Python code (or other
languages) is READ a hundred times as often as it is written.
Readability counts!

Here's a question: is it possible to implement this with a Python
module, or is that absolutely not a thing that can be done? I've seen
some odd things done with modules.

Look up Judy arrays. Specialized data structure for this. It's got a
simple API, but it's incredibly complex and architecture-specific under the
hood.
People are always trying to optimize, but there are limits to how much you
can do on generic data structures (and how much you can do in general),
value-returning form of try... except...
But perhaps the two of them together are too much of a change.

Perhaps the time isn't ripe for this, and perhaps it never will be, but
UTF8 seems to be handled by just about everything these days. I suspect
this is a crazy suggestion, but on the other hand perhaps people looking

lot to the REPL nature of the testing/experimenting process.
