ok, when is that needed ...

\ifdim\scratchdimen=10pt
   \expandafter \expandafter \expandafter \afterwards
\else\ifdim\scratchdimen=20pt
   \expandafter \expandafter \expandafter \afterwards
\else\ifdim\scratchdimen=30pt
   \expandafter \expandafter \expandafter \afterwards
\else
   \expandafter \afterwards
\fi

can be:

\ifdim\scratchdimen=10pt
   \expandafter \afterwards
\orelse\ifdim\scratchdimen=20pt
   \expandafter \afterwards
\orelse\ifdim\scratchdimen=30pt
   \expandafter \afterwards
\else
   \expandafter \afterwards
\fi

which of course will not the 3 or 6 expandafter folk who like to impress 
us so that can go to the top of your growing todo

well, it's a good sign ... so you can put it in a cont-loc.mkxl 
somewhere in texmf-local/tex/context/user (run mtxrun --generate 
afterwards) and be protected for life

you can test this with

\permanent \def \jim {okay}

\def \jim {oeps}

here i have it enabled by default
