\starttext

\unprotect
     \def\number_two{two}
\protect

\startluacode
     userdata = userdata or { }
     function userdata.number_one() context("one") end

     userdata.number_one()

     context.unprotect()
     context.number_two()
     context.protect()

     context.pushcatcodes("prt")
     context.number_two()
     context.popcatcodes()

\stopluacode
