Subject: good writing in Ruby...

I know I can write it the 'ugly common way' (loop)
but I'd like to see how it can be done the Ruby way ... (I am a newbie...)

here is an array
roles = [ "a", "b", "c", "d", "e" ]

Depending upon a variable 'user.role',
I would like to  suppress all elements in the array , less or equal to 
this variable

ex :
user.role = "a"    #=> roles = ["b", "c", "d", "e" ]    		"a" deleted
user.role = "b"    #=> roles = ["c", "d", "e" ]   		"a", "b"  deleted
user.role = "c"    #=> roles = [ "d", "e" ]   			"a", "b", "c" deleted
user.role = "d"    #=> roles = [ "e" ]    				"a", "b", "c", "d"  deleted
user.role = "e"    #  do nothing

thanks for your tips
