I have a similar experience, I learned English much later than my first programming languages, and picking up some keywords and basic APIs was never an issue (it was BASIC and C/C++ at the time). Maybe I would occasionally look up in a dictionary what is 'needle' and 'haystack' in a code snippet, and I was puzzled by the ubiquitous "foo, bar, baz", which to my relief turned out to be equally cryptic for the native speakers. I still don't feel about code as a kind of English prose, it occupies a separate part of my brain, compared to the natural languages.
