Compiler Warnings

In complex macros, that would for instance implement some domain-specific language, it would be benefitical when the macro could point to subform in question. The compiler-warn function does allow you to do that.

compiler-warn form format-control &rest format-arguments

Function

Issue a warning about the form form. When possible implementation specific means are used to point the finger at the form, so that eventually SLIME or whatever IDE could highlight the context. When not available or not within the compiler, a normal warning is issued.

Obviously this does not work if form is an atom.

To narrow down the context you could setup a next best context with compiler-descend.

compiler-error form format-control &rest format-arguments

Function

Same as compiler-warn, but signals an error.

compiler-descend form &body body

Macro

The compiler-warn function could point the finger at the form warned about, if it is an atom. A next best (outer) choice could be given by compiler-descend.
