Thanks for the PR!

You can maybe pick a more readable name than sw and keep the same output size.

@agatti - done.

I had tried to follow what was here:

• s: (StreamReader)
• c: "ord of most recent character"
• pc: "previous character"
• t: "timestamp of most recent character"
• pt: "previous time"

... with sw as stdout.write. I now renamed this to stdout_write.

Regardless, confirmed - yes, the output size remains the same at 2,955 bytes.

Thanks!

That naming scheme can work for global entities (eg. classes, functions, variables), arguments in function declarations, and class members. Those names are retained in the MPY file once compiled, but local variable names get discarded when compiled.

Understood, but everything we're talking about here is all at the same scope. :-) So maybe those should be renamed as well...

Point taken, then how about write? :)

Oh, and feel free to squash things into one single commit while you're at it.

Still, that's a nice change you've made there - I wonder where else in micropython-lib these modifications can be applied to.

@agatti - agreed, updated, and squashed.

Great, thank you!
