I agree.

Generally I am for keeping the language tidy. Because most times you don't do
this, later something comes back to bite your butt.

The following things are mostly off topic for this Bugzilla entry:

If your program is composed by only 1 module (like when you write very short
programs), then in my opinion it's not necessary to give it a module
declaration.

The module declaration is "infrastructure". Infrastructure is very useful when
programs grow bigger, but being forced to put infrastructure when you don't
need it, that is in very small programs, is a waste of energy.

I agree.


> for no benefit IMHO.

Walter has said there is some benefit (but I don't remember what). Even if this
is true, then I think such cases are special. And it's generally bad to break a
tidy convention for some special cases. If those cases are so important then
they should have a special "syntax", leaving the much more general case clean
of 1:1 between module name and file name.
