\ for string continuation
Context: Strings are frequently-used in ZGL. Being able to break a string across multiple lines while suppressing newlines helps ergonomics.
The ZGL grammar will allow
\ as a string continuation character for strings.
It works the same way as it does in Rust:
when an unescaped U+005C character (\) occurs immediately before the line-break, then the U+005C character, the line-break, and all whitespace at the beginning of the next line are ignored.
Consequences: This requires simple changes to the parser and syntax highlighters.
