Does Puppet have any genuine concept of truth and nil that survives the
interface with Ruby? has_variable? only returns false if a variable has
never been assigned a value at all in the enclosing scope; there is no
way to assign undef to a regular variable (as opposed to a resource
parameter) within a scope and so make it undefined for the template.
It would be a very useful thing to be able to do; makes for much cleaner
code. Have I missed something?
