// Semantic check step 1 does not have the notion of context and scope.
// It just gathers non-local names into a symbol table and check for uniqueness.
//
// Only declarations (non-locals) are visited and a symbol table is created.
//
//
// In order to debug symbol table just enable the GRAVITY_SYMTABLE_DEBUG macro
// in debug_macros.h

// Semantic Check Step 1 enables to resolve cases like:
/*
		function foo() {
			return bar();
		}
	
		function bar() {
			...
		}
 
		or
 
		class foo:bar {
			...
		}
 
		class bar {
			...
		}
 
		and
 
		class foo {
			var a;
 
			function bar() {
				return a + b;
			}
 
			var b;
		}

// It's a mandatory step in order to account for forward references
// allowed in any non-local declaration
