Hello all, With minimal example
{\tracingassigns=1\begingroup\catcode`\+=11\endgroup}
\bye
pdfTeX writes the expected data to the log:
{changing \catcode43=12}
{into \catcode43=11}
and with \tracingall or similar also reports restoring catcodes at the
end of groups. That's not the case with LuaTeX: no catcode logging. Is
this deliberate or a bug? If it's deliberate, what's the reasoning: it's
tricky for doing a diff against pdfTeX log.
