Concatenate strings at compile-time

[Jonathan M. Wilbur via Digitalmars-d-learn]

I have a method that cannot be @nogc only because it concatenates 
strings for a long exception message, as seen below.

            throw new ASN1ValuePaddingException
            (
                "This exception was thrown because you attempted 
to decode " ~
                "an INTEGER that was encoded on more than the 
minimum " ~
                "necessary bytes. " ~
                notWhatYouMeantText ~ forMoreInformationText ~
                debugInformationText ~ reportBugsText
            );
Those variables you see are immutable. Is there a way that I can 
combine these strings together at compile time, rather than 
having a really long string that exceeds the 120 hard line-length 
limit?
