I know this style, from Oberon. I played a bit with Oberon but I found I want something more like a proper language and of course more powerful so I choose GM2.

If I just IMPORT EXAMPLE; the procedure inside EXAMPLE doesn't automatically available to me but I have to prepend EXAMPLE. before every procedure I want to use. It's very time consuming and imagine if our module has a very long name... it will be a nightmare.

You should not use unqualified imports.

FROM Foo IMPORT Bar, Baz, Bam; (* VERY BAD STYLE *)

Use qualified import instead.

IMPORT Foo; (* PROPER/CLEAN STYLE *)

This way you do not need to import identifiers one by one.

This also saves you the hassle of making up longer more specific names.

Instead of

FROM StringLib IMPORT stringsAreEqual;

IF stringsAreEqual(str1, str2) THEN ...

you do

IMPORT StringT;

IF StringT.equal(str1, str2) THEN ...

I found it's too time consuming to write a long list of import, export. Is there any syntax to import everything from a module? e.g: FROM EXAMPLE IMPORT */ALL/EVERYTHING/... or IMPORT EXAMPLE.*? Python has a syntax like this: from example import *; which I think heavily influenced by M2.

I wonder the same thing for Export, too. Thanks.
