I suspect you’re right, within the confines of the weak variant of the hypothesis. As a trivial example, users of functional languages are more likely to think up solutions using recursion, and users of imperative languages are more likely to use iteration.

To my knowledge, all modern programming languages are Turing Complete, which is to that every one of them can express any idea. After all, Guy Steele built an entire text editor in a functional language!
