· handle named exit from a method
· check string parameters more strictly

· refuse --executable-file-name on names without a suffix
· do not create .gpi files from incorrect input
· allow passing variant selector by reference in default mode
· noinline attribute
· check for identifier redeclaration in records and parameter lists
· set constants are compatible with packed sets
