Look up Object#method and Method in the docs:

you can do ['aaa'.method(:size), 10.method("+")]

UnboundMethod could be useful as well.

Other than that, its possible to call methods by name. I you just need
to call methods on one object, it is enough to store just their names
(preferably as symbols):

methods = [:size, :length, :whatever]

then you would for example do: methods.each {|m| 'aaaa'.send(m) }
