Subject: Incorrect return of the TkFont configure instance method when no value

Hello,

I already posted this question to the ruby-core mailing-list, but as I 
received no answer, I suppose that it was not the right place :-)

I would like to get the size of a TkFont.
It could be done with something like ...

require 'tk'
font = TkFont.new...
...
size = font.configure :size

... as it is descibed in the Tk documentation (configure with an 
attribute without a value get the value of this attribute).

Unfortunately, this code returns the font object instead of the size 
attribute.
It is confirmed in the configure_core_tk8x method in 
ext/tk/lib/tk/font.rb file (line 1328) :

def configure_core_tk8x(font, slot, value=None)
...
 self
end

So my question : is it a bug or there is another (specific ruby) way to 
get the font attributes ?

Thanks and regards,
Lionel Maiaux
