When using an idiom such as:
def func(*args)
# some code
end
What is the meaning of *args? Googling this specific question was pretty hard, and I couldn't find anything.
It seems all the arguments actually appear in args[0] so I find myself writing defensive code such as:
my_var = args[0].delete(:var_name) if args[0]
But I'm sure there's a better way I'm missing out on.
