module.call(<string>)

Call a named virtual module.

If you have a virtual module, then you can call it based on a dynamically expanded string. See mods-available/home_server_pool for a worked example.

Example 1. The virtual module in mods-enabled/pool1

redundant pool1 {
	load-balance "%{Calling-Station-Id}%{User-Name}" {
		radius1
		radius2
		#  ... other modules
	}

	#
	#  This policy will be run then the above "load-balance" section
	#  fails.
	#
	group {
		#  ... policy ...
	}
}

You can then call the module at run-time.

if (User-Name =~ /@example.com$) {
	%module.call('pool1')
}

The argument to the function is a string, which can be taken from anywhere. e.g. an SQL query, LDAP query, or created dynamically by concatenating string values.
