I notice that alot of people really hate gotos...
But why is it sooo bad can someone tell me that???

eg. this little snipet to eat spaces andnewlines in a textfiles
to get to the first character

look_ahead(in_file,ch,bool);
<<start>>
while bool loop
  skipline(infile);
  look_ahead(in_file,ch,bool);
end loop;

if ch=' ' then
  while ch=' ' loop
    get(infile,ch);
    look_ahead(in_file,ch,bool);
  end loop;
  goto start;
end if;

Start_reading the words

I assume this is a typical example of bad goto use
but I canot figure out why, I think it is nice and easy 
to read and it takes care of potential 
' ',' ','\n','\n',' ',' ','\n'

I realize everything is posible to do without gotos 
but I canot figure out why it is so horible.
Please enlighten me.
Is goto statments particular slow?
