It's not just syntax. If the semantics and design patterns are different, then no matter if you call it (>>=) or bind, you won't be any closer to understanding the code; this is the "people who do not work in the language" part.

Would you expect to understand Forth or other concatenative languages even if all the operators are named?

The new set of semantics and patterns are the part that take time to understand. The syntax is not really the actual stumbling block.
