The basic syntax is very similar to the C# syntax, however there are
some enhancements / changes at various places. For example namespace
prefix in type declarations, see at the bottom of [1], construct
properties, see [2], differences in the declaration of interface
members, see [2], differences in object creation, see [3], signal vs.
event declaration syntax, see [4], or non-null types, see [5].
