Thanks for the explanation, Luke! I’ll keep this behavior in mind.

That’s the interim solution I am using right now (manually precompiling most
functions), but I generate quite a lot of closures dynamically in my code and
the potential performance loss is a bit worrying… I don’t think the current
behavior is expected based on what the documentation says.

Forgot to add: you could define f_env like this to get it compiled:
f_env <- local({
cmpfun(function(x) {
for(i in 1:1) x <- x + 1
x
})
})
Not as convenient as JIT, but it gets the job done...
