Incidentalley this allows for

   count func (a,b) => ...
   in out (a,b) => ...
   of if (a,b) => ...

Wonderful language, wonderful.

The letters have to be in order so maybe this will not work?

That's right, "in" works, but "count" and "of" don't.

Here are some of my favorites:

union

funi

funion

fution (sounds like fussion)

fu

fuc

fucton (as noted by a fellow commenter)
