Quoting the speck (lex.html)

Decimal Literal, L Suffix       Type
0L .. 9223372036854775807L      long

-(9223372036854775808L) is invalid b/c it is parsed as "- intLiteral"

Bug is not in DMD.

OTOH: should it be?

Seems to be according to the spec. But for me it is not logic that I can write
0x8000_0000_0000_0000L but not -9223372036854775808L.

bugzilla digitalmars.com changed:

           What    |Removed                     |Added
----------------------------------------------------------------------------
             Status|NEW                         |RESOLVED
         Resolution|                            |INVALID





The compiler is behaving correctly. The - is applied after the numeric literal
is processed, and 9223372036854775808L is out of range.
