Atom koan is trying to demonstrate that booleans are actually atoms. Writing it as
:true
and:false
in the assertion upfront would make it more obvious, because the learner would likely be expecting to entertrue
andfalse
in the blank area. Solves #226.Also Keyword List koan had a "non keyword list" for no reason, changing it to a keyword list keeps to the spirit of the koan and reduces confusion. Solves #222
