Surprising change in function inspect()

Surprising change in function inspect()

[Tomas Hala]

Hi all,

using the source code

======
\starttext
\startluacode
  d={} d.data={"a",0} d.tabulka=function () context("pokus") end 
  inspect(d)
  d.tabulka()
\stopluacode
pokus
\stoptext
======

I discovered quite surprising change in the output of inspect:

TL2019:

table={
 ["data"]={ "a", 0 },
}

TL2018 and older:

table={
 ["data"]={ "a", 0 },
 ["tabulka"]=load("\27LuaR\0\1\4\4\4\8\0\25�\13\
\26\
\4\0\0\0\4\0\0\0\0\0\2\4\0\0\0\6\0@\0A@\0\0\29@\0\1\31\0�\0\2\0\0\0\4\8\0\0\0context\0\4\6\0\0\0pokus\0\0\0\0\0\1\0\0\0\0\0\14\0\0\0=[\\directlua]\0\4\0\0\0\4\0\0\0\4\0\0\0\4\0\0\0\4\0\0\0\0\0\0\0\1\0\0\0\5\0\0\0_ENV\0"),
}

Is there any way how to persuade the current inspect to add functions to the output as before?

Best wishes

Tomáš

you can always use:

   print(table.serialize(d))

Thanks for the explanation. But there is the difference -- serialize says
only the memory address and not the stuff there. Have we got any other tool?
The reason why I am looking for any replacement is the intention 
to show students how it looks inside.
