Any interest in having an option to read symbols ending in ':' as  
keywords? (like srfi 88)  I personally find this prettier and easier  
to read.

(greet "John" last: "Doe" hi: "Howdy")

I'm imagining that we could turn it on/off with something like

#reader-options ...

at the top of a file?  That would preserve any existing code that  
used symbols ending in ':'.
