By pvande:

The disagreement we seem to be having here is about whether referencing a non-existent partial (i.e. there is no file on disk corresponding to the partial name) should raise an exception. I hold that, for user friendliness, referencing a non-existent partial should not interrupt template parsing -- though it may raise awareness through a secondary channel. An configuration setting to enable or disable exceptions would also be a reasonable approach.

Is a file-existence check actually prohibitively expensive?
