We use "bind" as a method name in the standard library. Other possible
keywords are likely to have the same problem - it's not a space rich
in suitable terminology. Opening the statement with "|" would suffice
though - it's otherwise invalid at the start of an expression, so it
gives a lot of freedom in the grammar details for the rest of the
statement, including the spelling of the assignment details (you could
even reuse a single "=", something like ":=" or "()=" or else Terry's
TIE fighter notation "(=)")

Cheers,
Nick.
