I could have written this instead:

a :: Something a = a

Which is nicer than undefined.

nope, it isn't.

Well, it depends on what you think is nicer. For me it looks shorter than undefined and it don't rely on the library.

And then let a = a is more defined than the other two... only the equation is _|_, not the value that is "assigned". Value that is equated? Term? Jonathan, please beat me.

This is over my head. If let a = a is more defined, then why (print a) won't stop ? ________ Information from NOD32 ________ This message was checked by NOD32 Antivirus System for Linux Mail Servers. part000.txt - is OK http://www.eset.com
