Something like

text = "11\n abcd \n22"
answer = text =~ "11.*22" :: <various possibilities>

and have it find the entire string. The default behavior is to stop 
matching when it encounters a newline. There is mention in the 
Text.Regex.Posix docs of a flag to control this behavior, but it is not 
easy to figure out from the docs how to provide flags. The left-hand side 
of the =~ is a very complex type.
