Minification error on del[]

[chopin]

Hi again.

I encountered an error during minification when running Transcrypt without -n option. Following is the corresponding source line:

del handlers[id(xmlHttp)]

Following is the error message:

network.pyjamasHTTPRequest.pretty.js:299: ERROR - Parse error. Invalid delete operand. Only properties can be deleted.
                delete __k__ (handlers, id (xmlHttp));
^

This error is not raised when running Transcrypt with -n (nominification) option.

Thanks.

I am not able to use minification because of this error. I hope that this bug is fixed so that I can use minification. Thanks.
