In Lua, you can't put a line break in the middle of a string. However, ever since Lua 5.2, newlines are equivalent to whitespace everywhere else.

This is incorrect. Newlines are not equivalent to whitespace *in strings*. Whitespace is significant *in strings*.

This is a feature, not a bug.

Note that I'm asking for multiline strings that support escapes, not the removal of raw strings.

(I'm fine with line comments the way they are, tho)
