echo() and print() are treated as a special feature
Because of some features specific to PHP (like short echo tag), PH7 Engine implemented echo() and print() builtin functions twice - as standalone function and as special construct. Thereby it is possible to call print() and echo() without brackets. In Aer, there is no such need and print() should be just a builtin function. There is also no need to maintain both functions. Thus echo() can be removed.
I was thinking about keeping print and removing echo. Do you think, this is bad idea?
