Function factory function, and other undocumented functions

[fakuivan]

I recall once seeing a function that you could pass a vector of arguments and an expression, and it would return a function object, built using said parameters. Does anyone know the name for it?

There are a couple of functions I was able to find, but there's no documentation written for them, like ``bloc`` and ``backquote``. Is there any way I can extract the name of these functions without disassembling the firmware blobs?
