The ETA framework relies heavily on template mechanisms to work. This provides a clean interface and good performances. A drawback is that the compilation errors that one can get when making a mistake in the expression are extremly complicated and nearly impossible to understand for non-expert developers.

We explain here how to find out where is the problem and what are the exact criteria that makes an expression well-formed or ill-formed.
