actually, \omcirkeld has been part of context for years already -)

For MP lovers, i add an alternative:

\startreusableMPgraphic{omcirkeld}
   draw fullcircle xyscaled (OverlayWidth,OverlayHeight)
     withpen pencircle scaled OverlayLineWidth
     withcolor OverlayLineColor ;
\stopreusableMPgraphic

\defineoverlay[omcirkeld][\reuseMPgraphic{omcirkeld}]

\defineframedtext
   [omcirkeld]
   [frame=off,
    background=omcirkeld,
    width=fit,
    offset=1ex]

\setupcolors[state=start]

\omcirkeld [framecolor=green] {Frans}
