Macro: SB-EXT:WITH-CURRENT-SOURCE-FORM

In a macroexpander, indicate that FORMS are being processed by BODY.

FORMS are usually sub-forms of the whole form passed to the expander.

If more than one form is supplied, FORMS should be ordered by specificity, with the most specific form first. This allows the compiler to try and obtain a source path using subsequent elements of FORMS if it fails for the first one.

Indicating the processing of sub-forms lets the compiler report precise source locations in case conditions are signaled during the execution of BODY.

NOTE: This interface is experimental and subject to change.
