That would take me too much time to write down :-), but I can tell
you that this \installlanguage didn't work because \lefthyphenmin
and \righthyphenmin are 'global' during the course of the paragraph,
only the final value is used (like for most paragraph parameters).

What will work, is setting the TeX primitive \language to a value
that does not have associated patterns (-1 is a possibility, but
usually 255 also works). In the next bit of context code, there
will be no hyphenation:

   \starttext
   \normallanguage -1 \hsize = 0pt \input zapf \language[en]
   \stoptext

(babel has a language definition 'nohyph', precisely for this)

Hope this helps,
Taco
