It's an interesting idea,       though due to the way C++ parses, any new operators would generally       have a fixed precedence. This might lead to them having surprising       precedences to users of a particular domain where paper notation is       different from whatever precedence was chosen for C++.              That said, more opportunity for DSLs and infix notation is probably a       good thing.              > Actually now that I reflect on it, << and >> have sometimes been       > used in mathematics to mean 'much greater than' and 'much less than'       > so using them for bit shifts is already a little suspect (to those       > who wish to confine operator overloading to a single overarching       > meaning)              That would be an entertaining prospect, having to specify "much" for       this context.              gcc -fmuch=1e9 ...              -Ed                     --        [ See http://www.gotw.ca/resources/clcm.htm for info about ]        [ comp.lang.c++.moderated.
