ParsePluginSourceString parses the source attribute and returns a plugin.

ParseRef attempts to extract a referencable address from the prefix of the given traversal, which must be an absolute traversal or this function will panic.

Plugin encapsulates a single plugin type.

Reference describes a reference to an address with source location information.

Referenceable is an interface implemented by all address types that can appear as references in configuration language expressions.
