something like this ?
``` D
import std.array;
import std.algorithm;
udtComputers.byPair
.filter!(p => p.key != strComputerIDunwanted)

This seems really interesting :)

It's actually visually shorter than doing the filter.
Indeed; in a few very-specific situations I usually write code

and not on the details to access the

You still have an if, but the actual loop body doesn't have to
be nested, so it's easy to follow the control flow.

An associative array is not a range but a struct, so it is
extra work to create a range from the AA to apply range
functions.
You can get a range from it by using something like
std.array.byPair() but for this usage you would be better
