One thing bilingualism has allowed me to do is differentiate better between the words and the things the words represent. This is mostly driven by words from different languages that translate to each other, not sharing all meanings of words. Of course I cannot think of an example right now that usefully illustrates how this leads to insights. It has explicitly come up in some philosophical discussions with friends and family who were going down a path intellectually that was driven more by the language than what it represents. IMO, your programming language comparison is somewhat similar in that even knowing multiple, similar languages allows you to differentiate between the syntax and the concepts expressed by the syntax. E.g. different ways of constructing classes and objects in different languages will make you understand the core of OOP better, similarly to different ways to loop, etc.
