I just stumbled on this wikipedia article: https://en.wikipedia.org/wiki/Concatenative_programming_language

Seems like D falls under that category?

-S.

Not really. UFCS allows the syntax "x.foo.bar.baz", which is similar to a concatenative syntax, but the existence of "x" in the expression means it's not purely concatenative.

In a purely concatenative language, "foo bar baz" would produce a function that pipelines those three functions. "foo.bar.baz" in D would produce a compiler error.

import std.functional : pipe;
alias allThree = pipe!(foo, bar, baz);

Interesting, but I'd call that a concatenative sub-language at most. ;)

There's certainly some conceptual overlap between concatenative languages and D under certain conditions, but there's not much syntactic overlap.
