The lua manual also states that one should NOT rely on the implicit conversion of a string to its numerical value, and suggests the systematic use of tonumber().
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.
