Could we add possibility to assign field as invocation appropriate setter.

[fAns1k]

as an example kotlin doesn't have fields at all and uses KPropery<*> instead of. in this case we cannot assign value in the generated code.

Resolution:
complier could check whether filed exist or not to solve the assignment strategy. (field assigment or invoke corresponding setter).

We can, and it's a good practice. The thing is we'd better use some tool to follow strategy of field assignment. Imagine All those Immutables, AutoValue, etc.

@almozavr yep, to avoid boiler-plate like setParam() for each parameter.

@fAns1k partially fixed with a88a78b (kotlin action classes support)
