Is it possible to break a long line into multiple lines along method call boundaries?

Question

From multiple method calls:

result=long_name.long_name2(a,b,c,d,e,f,g).long_name3(h,i,j,k,l,m)

To something along the lines of:

result=long_name.
    long_name2(a,b,c,d,e,f,g).
    long_name3(h,i,j,k,l,m)

The backslash \ line continuation character does not seem to work for this purpose. E.g.:

# Not valid code
result=long_name.\
    long_name2(a,b,c,d,e,f,g).\
    long_name3(h,i,j,k,l,m)
