Yes it is.
takeNone() take a char from a string.
So you are going to append a char (with code 5) on the next line.
If you replace that line with:
s ~= 65;
it will print A. (65 is ascii code for letter 'A')

Are static ifs always checked outside of runtime? Is it
possible for a static if condition to be undeterminable outside
of runtime, or would such a condition throw a compiler error?

Depends on how you fill aTUs.
For example if you slice the original string, it will be
preserved in memory. That's why parsers keep parsed substrings by
duplicating them - this can result in smaller memory footprint.

Many thanks for the feedback yazd! I've tested the approach with
a large csv file and it works fine. Unfortunately csvReader seems
very convenient but it is no speed daemon. To my dismay it was
much slower (about 4x) than a simple approach I am using in
Python, which is essentially equivalent

If you're just looking at the data, use const. immutable becomes
more important if it is shared across threads or stored for later.
Functions that accept const will work with almost anything you
pass to it.

Nothing will help you get around this. You have to expose a

You should start a worker thread for this and then use message
