Dear Group and Mathematica staff.
In the functional programming spirit I am missing a postfix notation
for Map[ ].
Du to its clarity I often prefer the sequentiall postfix style
processing of expressions and data:
e.g.
data//F1//F2//F3
but what if our data is a List and the functions we want to perform on
don't have the Listable Attribute ?.
the clumsy solution now is:
data//F1/@#&//F2/@#&//F3/@#&
therefor I suggest a new functional operator, which e.g. could look
like this: ///
such that my favorit expression would appear in this nice and clear
form:
data///F1///F2///F3
In other words the new /// operator should temporarily activate the
Listable Atrribute for the affected function
any comments welcome
Robert
