Agree with kebab-case.

> Most languages have multiline literals, but what makes the Lua version great is that the beginning and ending marks are different characters. This solves the infuriating “unnestable quotes” problem string literals have, and you don’t have to escape all your literal \s.

That paragraph also uses “nestable marks”.

Nestable comment syntax is also nice. At least some MLs (eg SML) has it, that I know of.

Indentation-sensitivity can also solve similar problems. (Indentation does not have to exclude requiring graphic termination. A formal language can require both. Or just a helpful tool.)

(Also agree with 'kebab-case', although the name is new to me and a bit weird.)

What makes C-style comments unnestable?

/**/ could potentially be nestable, they are just not defined as such.

They are defined to be non-nestable. Any appearance of */ terminates the comment.

Scala has it too. (But OK, Scala is a kind of ML).

FWIW, Raku and XPath support kebap-case. If you really mean subtraction, you have to add whitespace.

That works, but isn't necessary in Raku. As long as the right side of the hyphen does not start with an alphabetic character, you're good:

my $a = 45; say $a-3; # 42

That's such a perl/raku thing, and I mean it in the best way possible.
