Multichar literals

The only thing I can imagine using it for is checking the magic
number in a file header. Like 'ZM' for a DOS exe.

But I'd prefer to just use a regular string for it... an integer
would be easily wrong due to endianness issues. (In the DOS
exe the header actually says 'MZ' if you read the file from
left to right. The PNG magic number is '.PNG' left to right,
but as an integer literal, it would be backward 'GNP.')

Seems like more trouble than its worth to me, but maybe
I'm missing something too.
