Zen? This is madness!

In my mind, Matlab's (Octave's) array based programming makes sense. This? This does nothing that I expected it to do!

replicate seems to pretty randomly takes a function. Is that an R thing? I think what confuses me most is that there is nothing about this syntax that tells me that "cumprod (rnorm (1000, 1, 0.03))" hasn't already been evaluated! I could not, for the life of me, figure out why replicate didn't just create 100 exact copies. For example, why does replicate(...) evaluate, but the internals don't? This is driving me crazy!
