arghh.... so many semicolons...
every line, but that's because JS actually ends every statement with a
semicolon. of course you can omit them but then the "automatic
semicolon insertion" happens.... I prefer to put them myself, thankyou
very much. (yes, i know that "modern JS developers" hate me for that)
but Lua doesn't work like that. in fact, in most cases you don't need
_any_ separator between statements beyond some whitespace, "x=4 y=6"
is perfectly valid, and at no point the parser insert anything between
those two. the semicolon is just a valid separator that helps to
disambiguate some dark corner cases.
apart from that, i liked the presentation very much. especially about
how modern C++ can help with the always uncomfortable case of managing
dynamic types on a statically typed language.
