It doesn’t predate sql and certainly not it’s use in mathematics. There are other options for concatenation so this is an unfortunate error.

Shouldn’t copy Erlang, otherwise might as well use it.

What do you mean by "it's use in mathematics"? To my knowledge <> was invented by Algol language creators to use it for inequality. There was no previous use in mathematics. And to my opinion, that was an unfortunate error.

Interesting, must have learned it so long ago… Pascal? that I conflated it with math class. Still ~1958 is rather venerable.

The plot thickens, apparently ++ is used for erlang. So I still find it a poor choice.

++ is for concatenating lists, it's not the only functional language that uses this.

Really though who cares? `=` is already misused in most programming languages.

When looking at new languages, getting the basics right is the first thing I look at. Clumsy string concatenation is a blocker in my business, which is like 75% of the code.

Actually in Elixir when doing string building you want to use "improper" lists which lets you very efficiently build up a string without doing any copying.

Oh ha, duh me, I did not consider it wasn't invented by Postgres.
