Without this patch applied the spec tests are invalid because they call
rvalue functions as if they were statements. This is a problem because
Puppet 2.7.x currently throws an exception if a rvalue function is
invoked as if it were a statement function. This exception from Puppet
is causing tests to fail.
This patch fixes the problem by changing the tests to assign the return
value of the functions to a variable. This fixes the problem by
invoking the functions properly.

In Puppet, it is not possible to reassign hash
values.
This function allows a reasonable way to perform
hash munging in Puppet.
