Hello,

Is there a more concise way of doing this with an Option:

if( something.isDefined ) goDoIt( something.get )

(Yes, goDoIt() could accept an Option but that just moves the if
statement into goDoIt.)

Thanks for any ideas.

Re: Better Option Use?

You can use foreach/map on Option classes.
something.foreach(goDoIt)
