# :discard
Marks a L0 top-level symbol as discarded
* IOW the marked symbol is treated as whitespace which is not passed to G1.
* Usage of the symbol in G1 is a fatal error.
* As is the symbol not being top-level (i.e. being used in some L0 RHS).
The clause can set an optional discard event for the symbol.
See also [discard default](wiki?name=discard+default) for the global discard event settings.
