I want to know if it is possible that I use strings without "". If I type *Prelude>foo bar* which actually I mean *Prelude>foo "bar"* However I don't want to type ""s.
I have noticed if *bar* is predefined or it is a number, it can be used as arguments. But can other strings be used this way? Like in bash, we can use *ping 127.0.0.1* where *127.0.0.1* is an argument. If not, can *foo* be defined as a function so that it recognize arguments like *bar* as *"bar"*? Thanks, Yi Lu
