I do this for things like:

$user_requirements = [filter1, filter2];

foreach ($user_requirements as $test) { if (!$test($some_data)) { return false; } return true; }

Is there any way to tell the analyzer to make sure that afunction of n arguments is passed in?

With a name like "asm" that comes as a surprise... Single Instruction Multiple Data[0] refers to low level processor instructions that are able to work across a range of data, e.g. video cards working on changing the values in a framebuffer with one instruction mapping across an entire buffer in parallel.
