Puppet users - Jun 2008 - Variable scopes and defined functions

This doesn''t appear to be documented in the book or the wiki (except
by the absence of documentation).

I have a series of node foo inherits bar {} in my site.pp.  This sets
up a chain like base -> workstation -> thinkpad -> thinkpadt43.

I have a function defined as puppet_file().  It takes the usual file()
arguments, but sets up the source parameter with the full puppet host
and file share etc, then concatenates the argument $source
appropriately.  I''ve also got some other arguments on puppet_file()
that I want to use to set up paths inside of a source array (which I
see Luke calls a bug, I call a useful feature).  If I pass them
explicitly, then everything works properly.  If I go:

node foo inherits bar {
  $variable = ''workstations''
  puppet_file {
    "mail_aliases":
      ......
  }
}

puppet_file doesn''t get the value of $variable inside of it.  Is this
scoping restriction deliberate?  If so, lots more typing for me!

And now that I think about it, I have a reason why this is the way it
is.  Inheriting variable definitions from the scope would lead to
conflicts between variable names and function arguments.  Defining a
variable called ''source'' could lead to some interesting file()
calls
where you''re just ensuring a directory exists.

At least I can define $variable way up in the inheritance chain, and
have that cascade down, overriding when needed.
