Subject: no method error (because of unknown variable type)

Hi !

Here is a little example:

file "Functions.rb":
#---------------------
def func(file)
    if !file.eof then #do something.
end
#---------------

file "main.rb":

require 'Functions'
file_1=open('bla.txt','w')
func(file_1)
file_1.close

I get an error message that eof method is undefined.
I presume that this is because ruby does not know that the "file" variable 
is going to become a File.object.
How do I solve this ?

Thanks.
