In any case, I cannot compare to a number:
\startluacode
     userdata = userdata or {}
     function userdata.numbersfname(name)
         return string.match(name, "%d+")
     end
   \stopluacode
\define[1]\numbersfname
       {\cldcontext{userdata.numbersfname([==[#1]==])}}
Untested:
\defineexpandable[1]\numbersfname
   {\cldcontext{userdata.numbersfname([==[#1]==])}}
I’m afraid it doesn’t work.

  \startluacode
    userdata = userdata or {}
    function userdata.numbersfname(name)
        return string.match(name, "%d+")
    end
  \stopluacode

  \defineexpandable[1]\numbersfname
    {\cldcontext{userdata.numbersfname([==[#1]==])}}

  \starttext
  \numbersfname{abc123}

  \numbersfname{\env{fname}}
  \doifelse{\numbersfname{\env{fname}}}{123}{yes}{no}
  \stoptext

Just curious about what the difference might be.

Many thanks for your help,

Pablo
