Just remark. In SQL Server for instance you can design query graphically but everyone (in my experience) just write it in text. I am trying to say that it would not be easy to go to higher level of abstraction. Graphical languages are not very popular. Human is a beast which thinks rather sequentially and text mirrors that behaviour.
If we want to drag people here making syntax looking familiar to them I am afraid that it is wrong approach. They will go anyway. I think when you choose language you have many more serious considerations. Especially when you know few other languages it does not matter if curly braces or not. Also I am afraid that we have relatively small community and instead of uniting we are going to split it to smaller incompatible camps.
