Created originally on Bitbucket by ClariseTG (Clarise TG)
In the following code,
(set:$var to "")
(if:$var contains "Roses are red")[Violets are blue]
(else:)[This poem is incomplete]
an error message will be generated, reading “the string "" cannot contain any values, let alone the string "Roses are red"”, rather than evaluating as false.
