In [https://github.com/nim-lang/Nim/blob/devel/compiler/commands.nim](https://github.com/nim-lang/Nim/blob/devel/compiler/commands.nim) , at command line option "newruntime",
I could locate `defineSymbol(conf.symbols, "nimV2")` and `conf.selectedGC = gcDestructors` So something like nimV2 and gcDestructors seems to exist. However, for this purpose, I expected (but failed) to find the new keywords `owned`, `sink` and `lent` in the lexer's token list. So, if not there, where are they?
