edebug-form-data

edebug-form-data is a variable defined in `edebug.el'.
Its value is

nil

• Automatically becomes buffer-local when set.

Documentation:
A list of entries associating symbols with buffer regions.
Each entry is an `edebug--form-data' struct with fields:
SYMBOL, BEGIN-MARKER, and END-MARKER. The markers
are at the beginning and end of an entry level form and SYMBOL is
a symbol that holds all edebug related information for the form on its
property list.

In the future (haha!), the symbol will be irrelevant and edebug data will
be stored in the definitions themselves rather than in the property
list of a symbol.
