I just came up the idea: why didn't they name the language "Goo", and leave "Gle" to the debugger? It would be more common for people to refer to the language itself than to its debugger.

Then again... http://en.wikipedia.org/wiki/Goo_%28programming_language%29 , although the homepage http://people.csail.mit.edu/jrb/goo/ suggests that that sort of thinking is not really in Goo's pedigree... even for 2003 that's not a pretty page.
Also, if you're suggesting "gle" as a debugger name, you're missing the joke. "ogle" is a verb meaning, approximately, "to look at", so it's a good name for a debugger. "gle" is not.
(Except that "ogle" is not actually a good name for a corporate-sponsored debugger, because "ogle" has sexual connotations. Which is why you should assume that this is a joke.)
