Dear gang,

The following, simple MWE gives an undefined control sequence error:

=======
% \usemodule[translate]
% \enableinputtranslation
\startluacode
-- context.usemodule({translate})
context.usemodule{translate}

context.usemodule({ "first" })

or

context.usemodule{ "first" }

context.enableinputtranslation()
context.darkgreen()
\stopluacode

\startTEXpage[offset=1em]

\translateinput[Hermes][Idris]

Hermes

\disableinputtranslation

Hermes

\stopTEXpage
=======
tex error > tex error on line 14 in file ./test-luacode.tex:
Undefined control sequence

<line 3.12>
\translateinput
[Hermes][Idris]
=======

The reason for the error is that the module is not being loaded.
Toggling back to context syntax, of course, works.

Reference: ConTeXt Lua Documents by Hans Hagen, page 22. The following
analogous code works:

\startluacode
context.startchapter{first}
\stopluacode

It doesn't work or at least it does not what you expect, the examples in
the manual pass strings ( "..." )
wherever text is expected while you pass a lua variable to the commands.
Passing variables only work
when the variable itself refers to a string, e.g.

translate = "translate"
