[Vala] Adding defer in vala?

[pancake <pancake youterm com>]

Go adds a new keywordnamed 'defer' that schedules the execution of a statement until a return is perfiormed. 
Something like.. I have to do x,y,z before leaving..

In vala we have a bit of automagic reference counting which can close filedescriptors or destroy objects 
automatically.

Do you think that it would be good for vala to support 'defer'?
