The lua manual also states that one should NOT rely on the implicit

Many thanks for your reply, Alan.
I guess that backwards compatibility should be important here, but I
hope there are stronger reasons for breaking it.
Many thanks for your help,
In addition to what others already explained, you should not depend on
features that are implementation dependent or might disappear. That said
...
\startTEXpage[offset=1em]
\ctxlua{context([[\lastpage]])}.
\stopTEXpage
Why do you convert \lastpage to a string using [[\lastpage]] which will
use the string to number conversion. In fact this automatic cast from
string to number in an addition might disappear from the language in the
future so don't rely on that.
You can just do:
\startTEXpage[offset=1em]
\ctxlua{context(\lastpage + 1)}.
\stopTEXpage
Or when in dount about what \lastpage is
\startTEXpage[offset=1em]
\ctxlua{context(\number\lastpage + 1)}.
\stopTEXpage
or if you really want to [[ ]]
\startTEXpage[offset=1em]
\the\numexpr\ctxlua{context([[lastpage]] + 1)}\relax .
\stopTEXpage
endless possibities here.
