Now watching some #PHP videos on the former #Lynda.com site ( now called #LinkedIn / #LockedOut Learning ) before I go back to the #Lua videos.
I had to take a time out from Lua because none of the (book and video) examples of "first class functions ... pass the function to that one" were working for me and I could not see why.
The odd thing is that the weird issues with scoping that I saw the past few days are gone today. Lua 5.1.5 on #Win10 1909 and Lua 5.2.4 on #Kubuntu 18.04, #Linux kernel 4.15
