+1 on the logic, but with a stylistic fix; chains like this should be
written fluent / comprehension style:
@value.
collect { |x| x.evaluate(scope) }.
collect { |val| val == :undef ? '' : val }.
join
In other words, you're just inserting:
collect { |val| val == :undef ? '' : val }.
in the pipe, and this should be clearer.
