Copy path name as value?

[TobiasNx]

Sometimes it can be necessary to copy the path name as value, at the moment we cannot do this.

Can you please add an example of your use case?

It could provide a solution for #349 :

we could introduce a function path_as_value

e.g.

input:

a:
	- dog
	- cat
	- bird

set_array("animals[]")
do list("a","var":"$i")
	copy_field("$i","animals[].$append.name")
	path_as_value("$i","animals[].$last.pos")
end

replace_all("animals[].*.pos","^.*(\\d*)$","$1")
retain("animals[]")

animals:
	- name: dog
	  pos: 1
	- name: cat
	  pos: 2
	- name: bird
	  pos: 3
