Hi,

I am trying to evaluate whether TCS currently allows to define an
expression syntax with dynamically typed variables, where the Injector
resolves the type.

Assuming I had this Metamodel:
class TypedElement
{
attribute type : String;
}

Class Variable extends Typed {
attribute name : String;
}

Class Expression extends Typed {
reference sequence container : Sequence;
}

Class Assignment {
reference var : Variable;
reference expression : Expression;
}

Can I somehow define a Syntax with TCS where
x = "Hello World"
lets the TCSInjector set property "type" of variable x to String, because
the type of "Hello World" would be String?

Or would I have to do this after Injecting as a semantical task
independent from the Syntax.

What you want to do is a kind of semantic analysis. You have to do this
after injecting. Note that you can use ATL for this purpose.
