How much do you think would break if protected luacall were treated

That kind of incompatibility is no option (I'm not going to analyze it
for mkiv let along other macro package usage

Thanks, this is indeed the workaround that I currently use. However,
the downside is that this has to tokenize the contents of \directlua
every time (and is therefore susceptible to surrounding \catcode
shenanigans) and it expands in at

Dear list,
I have noticed a somewhat strange difference between protected macros
and protected luacalls, namely that the latter cannot be expanded by
\the. In the example below I define a Lua function that prints
\numexpr 17\relax to the token stream and I call it once from a
protected TeX macro
