Symbols / Keywords
Keywords have to start, or end, with a single : character and are self-evaluating. They are a distinct type from symbols but can be easily converted.
:asd ; A keyword
; => :asd
asd: ; Another keyword
; => asd:
[= asd: :asd] ; It doesn't matter where we put the colon
; => #t
[= :asd [symbol->keyword 'asd]]
; => #t
