in the current luametatex upload, \scantokens (and also \scantextokens)
behave odd: They seem to act like \detokenize, except that spaces get
catcode other instead of catcode space:
\starttext
\edef\abc{\scantokens{\relax}}
\abc
\edef\abc{\scantextokens{\relax}}
\abc
\stoptext
used to result in an empty output file but with luametatex, it writes \relax
\relax to the output.
i'll look at it (i probably forget to set the catcodetable)
here is the generalized case:
\def\foo{!}
\edef\abc{\tokenized catcodetable \catcodetable {a\relax \foo}} \abc
\edef\abc{\tokenized catcodetable -1 {a\relax \foo}} \abc
