in reply to New String Concatenation In Perl 6?

I think this is the current list. String concatination is no longer . or _, it's ~. This doesn't mess up the smart-match (=~ or is that ~=?) operator, which is now ~~... or at least, it doesn't mess with it much.

    ~ is the unary operator to force string context.
    - is the binary operator to concatenate strings.

      ~ is both the unary string context forcing operator and the concatenate operator; - is still subtraction.

        Sorry, I really meant underscore. Anyway, tilda is indeed discussed as a possible concatenation operator. It makes indeed sense to use the same sign for the unary conversion to string and the binary concatenation. Also the underscore was less than ideal because it is used for identifiers. So that meant that it had to be surrounded by space.

        There are very long threads in p6l about operators in general and concatenation in particular. Indeed, the status of underscore as concatenation character is contested and tilda seems the main contendant but that does not seem a done thing.
