I propose the hygienic feature as a first project after we agree on the mission
statement.
\# declare all groff macros hygienic, default
.hygienic ON GROFFALL
\# declare all groff macros not hygienic
\# excludes .hygienic
.hygienic OFF GROFFALL
\# change given macros hygienic modes
.hygienic { OFF | ON } macroname ...
.macroset macrosetname macroname ... ?
.hygienic { OFF | ON } macrosetname ... ?
\# set hygienic mode
.hygienic { DISABLE | ENABLE }
It would help me stay disciplined in my own macro packages.
