So how about trying to make it a little easier to read, and using "->"
instead (a 4D way of identifying pointers)? The position of the symbol
indicates if we have are referencing or dereferencing. ->a is a
reference
to a (pointer to a), and a-> is dereferencing a (give me what a is
pointing
to).
Two reasons not to:
1) By-Reference parameters are not the same as pointers - in
particular, dereferencing is implicit, and referencing is only allowed
in the context of passing the parameter.
2) We already have a symbol '@' for marking by-ref parameters in
handler signatures, so surely it makes more sense to use that in its
directly equivalent position (on sending, as well as receiving).
General references (I don't think using the term 'pointer' is
appropriate) are a whole different kettle of fish which come with
dragons waiting to eat you all over the place...
Warmest Regards,
Mark.
