For Ruby 1.8.7 I get this result:

[1] pry(main)> def foo (a, b); p a; end
=> nil
[2] pry(main)> foo(1, 2)
1
=> nil
[3] pry(main)> foo (1, 2)
(pry):3: warning: don't put space before argument parentheses
1
=> nil

I get a warning but I do get the same result. Using Ruby 1.9.x it's as 
Ary said, it's a syntax error.
