Please read my original comment again.  I only oppose a comment syntax
which _requires_ explicit termination.  I don't oppose a comment syntax
which _allows_ explicit termination so long as the end of record also
terminates the comment.  My favorite syntax for what you have above
would go something like this:

!  table
int Transitions[NUMSTATE][NUMCLASS] = {
!  statenum   digit  number delimiter quote EOF EOL ...
!   0      !!   2,     5,     8,       15,   10, 19,
!   2      !!   4,     19,   ....
!   5      !!   ....
! ....

Here the comments begin with ! and end with !! or the end of line.  This
syntax even allows code (that doesn't include !!) to be 'commented out':

      a = b+c
!     x = a*(z+y)            ! trailing comment
      for ( ...) ...

Here the second statement was commented out.  The extra exclamation point
doesn't effect the fact that the comment ends at the end of line.  As I
say, this only works on lines that don't contain an explicitly termionated
comment.  But, since I prefer ifdef for removing code, this doesn't
matter much.  This can't be done with C, of course, since ! is an operator
in C.  But the C++ syntax ('//') might be extended (terminate comments
with '\\' maybe).
