It would be nice to simplify Strings especially in light of Raw String literals being added to Java which I suspect we will want to support at some stage. The thing is that slashy and dollar slashy strings aren't the same in various ways not just line endings. Changing them to be more the same (so that they could be considered the single and multi-line versions of one another) would be quite a large change. Obviously Groovy 3.0 is a time to consider larger changes than normal.
However, having just one example isn't enough for me to properly evaluate the merits of a potential change. I believe a full blown GEP would be required. E.g. would the proposed change alter the meaning of the following: m /c/ d Which can mean any of: m(/c/).d (m/c)/d m/(c/d) Another example, slashy strings are special in that they can appear in only certain places in the grammar, so you can't have: println /foo/ or any empty slashy string (it's a comment): def x = // 'foo' assert x.size() == 3 And these are just a few of dozens of cases we should look at if really trying to simplify string handling. We'd ideally include raw strings too. Some of the cases for slashy string won't change since removing the newlines won't change the underlying circumstances causing these restrictions but we'd need to check if any do or allow us to make further improvements if we wanted to. We would also need to cover migration tools in the GEP since we'd be breaking lots of existing code potentially. Cheers, Paul.
