I can't be the only one who's annoyed by language writers introducing arbitrary uncommon syntax apparently just for the sake of doing something new?

Lua's great little language but writing ~= instead of != is simply annoying. In this "Ko" language, it looks like they do returns with a colon, as in "return: x" -- why??? I won't even go into Rust picking up Perl's bad habit of looking like line noise with all the ASCII sigil usage in advanced code.

Also, any language which doesn't have a "hello world" example in its front page is doomed. Even such a wide-spread language as Python has code snippets practically first thing on its web page! This is not by accident!

I wonder why they preferred ~= over =/= ?

I would sympathize with using =/= for "not equal" because it is ASCII art for the traditional mathematical notation of using an equal sign with a line through it. Though it might be better just to permit carefully selected unicode characters such as https://www.fileformat.info/info/unicode/char/2260/index.htm

=/= is disappointing as art because it is too wide, but it has obvious mnemonic power.

Would you object to =/= as "arbitrary uncommon syntax" because it is poor art? Does its mnemonic power save it from the criticism of being "new for the sake of new"

MATLAB also uses ~= but I am not certain that is where Lua got it from. (The paper on the history of Lua does not say...)
