+	  no_invisible_vars isn't set

+	  code that eventually wants to assign a value to the variable; will not
+	  skip invisible variables; currently identical to find_variable
+	- find_variable_no_invisible: new function, finds the first visible
+	  instance of variable with a given name in the variable context chain;
+	  eventually will be used to replace find_variable; separate right now
