"Apply" method to array?

ruby-talk
1

Hi,

This is a newbie question:

Is there a way to apply (as in Lisp, Scheme and the like) a method/block
to an array, so that the elements of the array become the arguments of
the method call. Something like:

a(1,2,3) ~~ a.apply([1,2,3])

Cheers,
Thomas.

Like this?
a(*[1,2,3])

  • is used in argument list to unpack array contents to arguments (like
    here) or to pack arguments into an array,like in “def mymethod(*args)”
