Code can be copyrighted; ideas can't be.

Yes, but the syntax of the programming language is more than just an idea.

Copyright-article[1] at Wikipedia says that "Copyright is a set of
exclusive rights regulating the use of a particular expression of an
idea or information."

So, for example, the idea of look-behind assertions can't be
copyrighted as it's an idea.

But what about a particular form chosen to express that idea (e.g. to
use <before pattern> to denote look-behind)? Can this be copyrighted
as it's more than just an idea?

ps. I'm asking this because I'm thinking of creating a (simple)
programming language by myself, but I'm unsure about how much syntax I
could copy from any existing programming languages.
