Well, with C language it's pretty much the same. You are supposed to "just" never write (or rather, most of the time, to just not execute) anything that is UB. And lots and lots of people to this day continue to believe that

The US legal system never ceases to amaze me. Why indeed should a state enforce a law? Like, one of those anti-discrimination laws?

You have very interesting ideas on how the world should be run. A pity that others ignore them and just do whatever suits them better.

Yes, but why C had that syntax? Oh, right, because it didn't use if-then[-else]-end for the conditional statement, and reusing if(cond)[-else] with prohibited braces would be awkward. Oh, and Lua most famously does not accept express

Well, I believe there could be some complications with parsing related to the fact that Lua grammar doesn't really requires semicolons between the statements. But other than that, yeah, detecting "if" in the expression positi
