… when using const as decl

Summary

When reexports dynamic, runtime code will like this:

var__WEBPACK_REEXPORT_OBJECT__={};for(var__WEBPACK_IMPORT_KEY__inpath__WEBPACK_IMPORTED_MODULE_0__)if(__WEBPACK_IMPORT_KEY__!=="default")__WEBPACK_REEXPORT_OBJECT__[__WEBPACK_IMPORT_KEY__]=()=>{returnpath__WEBPACK_IMPORTED_MODULE_0__[__WEBPACK_IMPORT_KEY__];}

However this getter only access variable__WEBPACK_IMPORT_KEY__ when it really gets invoked, but the__WEBPACK_IMPORT_KEY__ is declared usingvar, which is in global scope not block scope infor stmt.

That will cause every getter access the last__WEBPACK_IMPORT_KEY__ in the end.
