Hi, I observed a slight problem in deparse(): it will add spaces around most operators except /. I wonder if this is easy to fix. I know this is quite trivial, but I will appreciate if / is not treated as an exception. Examples:
It's easy to change: take a look at src/main/deparse.c. The operators that are labelled as PP_BINARY2 get no spaces. Looking in src/main/names.c, we see those are /, ^, %%, %/% and :. But clearly this is by design, and I think it's unlikely to change. Duncan Murdoch
