Commands that should be use in token.set_macro must already exist. But while it is easy to predefine a command like \blub it seems not to be possible to do it with commands consisting of a \ with a non-letter.

perhaps --[==[ luatest.lua ]==] token.set_macro("foo",[==[\blub\csname !\endcsname]==]) %%test.tex \tracingall \def\!{[hallo!]} \def\blub{[hallo]} \directlua{require"luatest"} \show\foo \foo \bye (untested) -- luigi
