or returns the logical disjunction of all given arguments (i.e.
a || b || c || …). Each of the arguments must be convertible to booleans.
(or false false)➜false(or false false true)➜true
expris one or more arbitrary expressions.

At least one of the expressions must coalesce to true for the function to
return true.
or executes all expressions in their own contexts, so nothing is shared.
