"error" would be just a single function that is available in the context 
parameter. There would be many others. From the DIP:

* The arguments used when the compiler was invoked

* Functions for emitting messages of various verbosity level, like 
error, warning and info

* Functions for querying various types of settings/options, like which 
versions are defined, is "debug" or "release" defined and so on

* In general providing as much as possible of what the compiler knows 
about the compile run

* The context should have an associative array with references to all 
scoped variables at initiation point.
