Unable to parse deep expression when a function is in the middle

[nikolayandr]

Hi, interesting case

To reproduce: Parse t1.t2(v).t3.c1 = @v. Exception message: "Encountered unexpected token: "=" "=" at line 1, column 15. Was expecting one of: "(""

but the next similar expressions are parsed successfully: t1.t2(v).c1 = @v and t1.t2(v).t3.c1() = @v

Expected behavior: t1.t2(v).t3.c1 = @v is parsed into EqualtTo expression
