Negative numbers use unary minus. String and character literals support C++17 simple escapes (`\' \" \? \\ \a \b \f \n \r \t \v`), one to three octal digits, and `\x` followed by hexadecimal digits (byte values only). Unicode escapes `\uXXXX` and `\UXXXXXXXX` encode valid Unicode scalar values as UTF-8 in strings; in CHAR they must be ASCII. Unknown escapes are errors. Built-in STRING is NUL-terminated, so `"a\0b"` is observed as `"a"`. Comments begin with `//` and continue to the end of the line. Declare variables before use.
