Subject: using a local variable for method calls

hello all,

first off, thanks for all the help this board/list has offered.  it has
been fantastic.

a workmate of mine and i are puzzling over this problem.  here is a bit
of pseudo code that represents it:

somehash.each_key do |key|
  update.key "something"
end

obviously there is a problem with using the "key" variable to make the
method call.  how can we accomplish this elegantly?  we've considered
this:

somehash.each_key do |key|
  eval("update.#{key}(\"something\")")
end

but that seems a bit cludgey.  does anyone have some advice?
