Why can't I change the color and style when using processisolatedwords?

Also \processwords is defined twice, first in syst-aux which is then
overwritten by the definition in supp-box.
indeed as the supp-box one has some advantages

anyhow, I tried to fix it (qualifies as dirty trick)

\defineframed[colored][foregroundcolor=red,foregroundstyle=\bfc\underbar,location=low]

\starttext

\colored{What}

\processisolatedwords {\input ward \relax} \colored

\stoptext

should work ok now. Of course you can consider other approaches:

(wifiyable):

\startluacode

     local words = 
lpeg.split(lpeg.patterns.spacer,io.loaddata(resolvers.findfile("ward.tex")) 
or "")

     for i=1,#words do
         if i == 1 then
             context.dontleavehmode()
         else
             context.space()
         end
         context.colored(words[i])
     end

\stopluacode

or without temporary array:

\startluacode
     local i = 0

     local function reset()
         i = 0
     end

     local function apply(s)
         i = i + 1
         if i == 1 then
             context.dontleavehmode()
         else
             context.space()
         end
         context.colored(words[i])
     end

     local splitter = lpeg.P(true)/reset * 
lpeg.splitter(lpeg.patterns.spacer,apply)

     lpeg.match(splitter,io.loaddata(resolvers.findfile("ward.tex")) or "")

\stopluacode

maybe I should add this variant ..
