+1
It also avoids the problem of having to make sense of nesting, e.g.
(b1 (c1 c2)): d1
True, but it introduces the problem of making sense of these:
+ b1 + b2 +: d1
b1 + + b2: d1
b1 + b2 b3: d1
Solaris 10 make appears to silently drop dangling and extra '+'
connectors - which is convenient
for handling macros that are empty when expanded. It also appears to
silently insert missing
'+' connectors if there are any '+' connectors in the target group.
Thus, I think Solaris make would
treat the following rules as equivalent to the ones above:
+ b1 b2: d1
+ b1 b2 b3: d1
