FVWM: Abort from function?

I want a function that will "windowshade rollup and lower window" or
"windowshade unroll and raise window". The following:

Mouse 0 T N MoveOrRaiseOrShade
AddToFunc MoveOrRaiseOrShade
+ C Raise
+ M Move
+ D Current (Shaded) ShadeAndRaise
+ D Current (!Shaded) ShadeAndAway

has a cute bug: if a window is shaded, both last lines are executed.

So I was wondering, is there an Abort function so that I can write

AddToFunc ShadeAndRaise
+ I WindowShade
+ I Raise
+ I Abort

Other solutions welcome too.
