I don't know the reason that parse behaves this way, it may be a bug. =20
It seems to be something to do with the automatic whitespace handling. =20
If you use the /all refinement which lets you handle whitespaces
some
does what you expect.
>> parse/all "a b c" [copy x some "a" (probe x) to end]
a
== true
