char.string literal enclosures

6.2:
. this string literals syntax:
""()
is expecting the string to have balanced paren's,
and if this can't be expected,
then any other enclosure should be usable: {}, [] .
. if no expectations can be placed on the string,
then it can be written [6.4: indented and]
with the enclosures on separate lines:
""(
...
)-""
