On the other hand pic (Kernighan's picture-drawing "little language")
is very finicky about where it accepts \ line-continuations, allowing
them in some places but forbidding them in others. For example, the
pic code


for j = 2 to 6 by 2 do { \
    for i = 3 to 7 by 2 do { \
        fine_space_interp_point at grid_point(j,i) } }


does NOT allow a \ line-continuation between either "for" and the
following "{". (Or more precisely, all my attempts to make such
produced the usual unhelpful pic syntax-error messages.) :(
