Hello,

why this code:

----
\def\GG{\ifmmode G_G\else$\GG$\fi}

\starttext
   \GG $\GG$ % OK
   \startitemize[][]
     \sym{\GG} \GG % OK
   \stopitemize

   \startluacode
     context.startitemize()
       context.sym([[\GG]])
       context("Abc")
     context.stopitemize()
   \stopluacode
\stoptext
----

fails with:

"

                              $\fi

"

I need to call "\GG" from within Lua, and the real macro name is created run-time (contrary to this MNWE; so to be \GG, \HH, \Fik etc. - the name is obtained from a Lua table as a string).

I cannot understand why all TeX calls are OK but the problem appears in Lua block...

Best regards,

Lukas
