=0A> Hi all,=0A>=0A> When writing a long expresion, one usually would like =
to break it into multiple lines. Currently, you may use a '\' to do so, but=
 it looks a little awkward (more like machine-oriented thing). Therefore I =
start wondering why not allow line breaking at an operator, which is the st=
andard way of breaking a long expression in publication? Here is an example=
:=0A>=0A> #the old way=0A>=0A> x =3D 1+2+3+4+\=0A> =A0=A0=A0=A0=A0 1+2+3+4=
=0A>=0A> #the new way=0A> x =3D 1+2+3+4+ #line continues as it is clearly u=
nfinished=0A>=0A> =A0=A0=A0=A0=A0 1+2+3+4=0A=0A:# the currently allowed way=
=0A:x =3D (1+2+3+4+=0A:=A0 =A0 1+2+3+4)=0A:# note the parentheses=0A:=0A:I =
think this is sufficient.=0A=0AThat works, but not in the most natural way-=
-the way people are customed to...why require a pair of parenthis when we c=
an do without them? Also, the new way does not affect the old ways of doing=
 things at all, it is fully backward compatible. So this just offers a new =
choice.=0A=0A> Of course, the dot operator is also included, which may faci=
litate method chaining:=0A>=0A> x =3D svg.append( 'circle' ).=0A> =A0=A0=A0=
=A0=A0 r(2).cx(1).xy(1).=0A> =A0=A0=A0=A0=A0 foreground('black').bkground('=
white')=0A=0A:Also, I dislike this for the dot operator especially, as it c=

=0AAgain, this only offers a new choice, and does not force anybody to do i=
