See for example Java's text blocks:

    The opening delimiter is a sequence of three double quote characters
    (""") followed by zero or more white spaces followed by a line
    terminator. The content begins at the first character after the line
    terminator of the opening delimiter.

    The closing delimiter is a sequence of three double quote
    characters. The content ends at the last character before the first
    double quote of the closing delimiter.

(https://openjdk.org/jeps/378) -- it would be nifty if the mandatory
linebreak was inserted automatically.
