decorator - Meaning of a list in the function call

Question

For the below function call (that contains a decorator), what is the meaning of the list [var_A, var_B] in between the function name and function parameters?

myfunction[var_A, var_B](var1, var2)

I've never seen a function called like this, with what looks like an extra set of parameters.
