Not my syntax, so I'm not 100% sure of why, but I suspect it's because that
argument isn't the same kind of vector we're used to. For one thing, it's
a vector of functions, not of floats. For another, I don't think it's
limited to five or fewer components. So it doesn't get parsed by the
same code that parses normal vector arguments. I expect one could still
make the angle-brackets optional, but that apparently just wasn't done.
