Can you provide an example of using those safer functions in this case?

Using the scope.lookupvar or getvar functions would be greatly preferable;
using `eval` in this context is Really Bad (TM) and could produce some
extremely bad behavior depending on the value of my_lan1.

Nevermind. Figured this out:
<% if defined?( eval "macaddress_" + my_lan1 -%>
...

Is there a good way to check that the fact in question actually exists prior to
doing an eval? Doing the below when there is no 'my_lan1' fact produces an
error.

In a template, is there a way to use a variable to reference another variable
name? For instance, let's say I have a variable 'interface', and in my template
I want to reference @ipaddress_$interface so that when interface = 'eth0' I get
the value of @ipaddress_eth0, but when interface = 'eth1'
