I’m assembling a list of Ruby community “usages” and I want to make
sure I haven’t missed anything important.
I have such things as: duck typing, threequal, spaceship operator,
singleton method, singleton class, splat or unary unarray,
multiple or parallel assignment, and (ehh) eigenclass.
Not all usages are considered official or will necessarily be
Terms that are extremely common outside our community and are used
identically can probably be omitted from the list.
