Rebol is very forgiving -- perhaps overly so -- in interpreting what you type.

You have no space after the colon, your full string is an identifier. Rebol 
parses it as a URL.  Compare these:

>> .a:10
== .a:10

>> type? .a:10
== url!

>> http://www.rebol.com:8080
== http://www.rebol.com:8080

>> type? http://www.rebol.com:8080
== url!

>> .a: 10   ;; note the space
== 10

>> type? .a
== integer!
