Subject: ruby lexer/parser

Just a short question concerning the ruby lexer/parser

irb(main):001:0> a=1
=> 1
irb(main):002:0> a.to_f * 10.0   #space before and after '*'
=> 10.0
irb(main):003:0> a.to_f*10.0   #no space before and after '*'
=> 10.0

irb(main):005:0* a.to_f *10.0   #space before '*' and no space after
'*'
ArgumentError: wrong number of arguments (1 for 0)
        from (irb):5:in `to_f'
        from (irb):5

so why does ruby think *10.0 would be an argument to .to_f?

In my opinion the ruby lexer sould recognize '*' as an operator, no
spacing should
have any influence on this behavior ...
