Function `dmd.escape.checkAssignEscape`

Given an AssignExp, determine if the lvalue will cause the contents of the rvalue to escape. Print error messages when these are detected. Infer scope attribute for the lvalue where possible, in order to eliminate the error.

				(
				

				  dmd.dscope.Scope* sc,
				

				  Expression e,
				

				  bool gag,
				

				  bool byRef
				

				);

Parameters

Name	Description
sc	used to determine current function and module
e	`AssignExp` or `CatAssignExp` to check for any pointers to the stack
gag	do not print error messages
byRef	set to `true` if `e1` of `e` gets assigned a reference to `e2`
