Operators ++ cannot be used in SARL

[gbasso]

When using nbValues++ or ++nbValues an error occurs:

for ++nbValues:

Invalid number of arguments. The method operator_plus(Object,
   String) is not applicable for the arguments (Integer)

for nbValues++:

The method +() is undefined

The operator "++" exists in Java, but not in Scala.

The question is: is SARL following more the Java or the Scala syntax?

My opinion is: SARL should be mostly inspired from Scale, but several operators may be added for whose who is coming from Java.

What is your opinion?
