Not really any other way to do it, create context (i.e. struct, or
stack) and have a delegate point to both it and a patch function.

Hello,
D-Language allows for anonymous functions.
Is there a way of elegant partial function application such as in
other (functional) languages?
A function "doemar" accepts a function with one parameter,
Another function g defined within mail accepts two parameters and
should be applied parti

Hello,
I am new with D and want to convert a c program for a csv file
manipulation with exhaustive dynamic memory mechanics to D .
When reading a CSV-file line by line I would like to create an
associative array to get the row values by the value in the
second column.
