Ambiguity of parsing numbers with underscores/methods

[Ingo Blechschmidt]

Hi,

    1_234;      # surely 1234
    1e23;       # surely 1 * 10**23

    1._5;       # call of method "_5" on 1?
    1._foo;     # call of method "_foo" on 1?

    1.e5;       # 1.0 * 10**5?
    1.efoo;     # call of method "efoo" on 1?
    1.e_foo;    # call of method "e_foo" on 1?

    0xFF.dead;  # call of method "dead" on 0xFF?
