why does \usemodule load the requested file with “prtcatcodes” settings

when nearly each module has \unprotect and \protect at the begin and

end of the file?

I ask this because of a recent question [1] on the list where a user

defined shortcuts for math. Maybe a module isn’t the perfect thing

for these things and he can put them in a environment but now comes

the next problem.

When you load a environment in this way:

  \environment myenvironment

  \starttext

  …

  \stoptext

the file is loaded again with prtcatcodes while in the following form

  \startproduct myproduct

  \environment myenvironment

  …

  \stopproduct

the environment is loaded with ctxcatcodes. While prtcatcodes make sense

for a module i can’t understand why they are used for environments.
