typescript - Different behaviour of "export = class" -

i writing external module (using amd) needs export single class. want import import myclass = require('./myclass'), therefore in myclass module use "export =" syntax:

export = class myclass {     // ... } 

this compiles without errors , produces reasonable js code:

define(["require", "exports"], function (require, exports) {     return (function () {         function myclass() { /* ... */ }         return myclass;     })(); }); 

next, try import it:

import myclass = require('./myclass'); var my: myclass = new myclass(); 

compiling gives me error @ "var my: myclass": "ts2304: cannot find name 'myclass'".

but, when change module export to:

class myclass {     // ... } export = myclass; 

everything works okay, produced js code seems same:

define(["require", "exports"], function (require, exports) {     var myclass = (function () {         function myclass() { /* ... */ }         return myclass;     })();     return myclass; }); 

as far can see, difference is, uses temporary variable before return, has no effect outside of closure.

so what's difference , why ts2304 error in first case? should not both cases work same?

should not both cases work same?

they should. please report error here : https://github.com/microsoft/typescript/issues
