If you're interested, here's a slider that extends the same sort of patching structure as those examples.

Some recent tricks I learned are: [scalar struct-name var1 var2 etc.( | [s pd-some-patch]

This dynamically creates a ds instance. Unlike [append], you can mix float and symbol variables in this message.

[pointer] | [list 20 $1( | [set some-struct foo]

Put the pointer in a list, which is then distributed to the second inlet of set in this example (usually saves one object)

You can also accumulate a list of pointers in any of the [list] objects. Then when you want to output, say, the 4th pointer in the list and get its variable "foo", use:

[list] | [list $4( | [get struct-name foo]

I haven't used that one much so I'm not sure if it works well with large lists. And if you delete one of the ds-instances the pointers becomes "stale".

Yeah, its a known issue, fixed in 0.42.  Try Pd-vanilla 0.42.

In abstractions as:
