Hello,
why this code:
----
\def\GG{\ifmmode G_G\else$\GG$\fi}
because in math mode \GG expands \GG which expands \GG ....
maybe you mean:
\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()

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
