    Evaluate each pair of arguments up to the last one as a (matcher, value)
    tuple, returning ``value`` if matched.  If none match, returns the last
    argument.

    The ``ifelse`` function is like a multi-level if-else statement. It was
    inspired by CFEngine's ``ifelse`` function which in turn was inspired by
    Oracle's ``DECODE`` function. It must have an odd number of arguments (from
    1 to N). The last argument is the default value, like the ``else`` clause in
    standard programming languages. Every pair of arguments before the last one
    are evaluated as a pair. If the first one evaluates true then the second one
    is returned, as if you had used the first one in a compound match
    expression. Boolean values can also be used as the first item in a pair,
    as it will be translated to a match that will always match ("*") or never
    match ("SALT_IFELSE_MATCH_NOTHING") a target system.

    This is essentially another way to express the ``filter_by`` functionality
    in way that's familiar to CFEngine or Oracle users. Consider using
    ``filter_by`` unless this function fits your workflow.
