Subject: In praise of ->
This is not a problem, but I thought that I might say one or two things
in favour of right pointing assignment before anybody influential gets
the idea of scrapping it!
Situation (a)
You have just typed a long complcated expression into the console and
you suddenly realise that you will need it later in the session. Just
append
-> something
to the end of the expression. You can do this with any recently
evaluated expression with the help of the up-arrow key (in Windows at
least).
Situation (b)
You have written a chunk of code and you want to see how it behaves for
various values of the scalar "fred". Just put
-> fred
at the start of the code block, type any number, then paste the code
into the console.
Cheers, Murray
