ExtendToPosition()
Extend the list up to position n. ExtendToPosition pads with 0 -- (number lists) or "" ; the WithItemsIn/Repeated forms pad by -- cycling through a given list (or the list's own items).

Softanza
o1 = new stzList([ 1, 2, 3]) o1.ExtendToPosition(5) ? @@( o1.Content() ) o1.ExtendToPositionXT( 8, :With = 5 ) ? @@(o1.Content())
Output
[ 1, 2, 3, 0, 0 ] [ 1, 2, 3, 0, 0, 5, 5, 5 ]

The extensions of this method
Each extension, and whether it exists for this method; an extension that exists combines with the others (FindSTCS).
Extension
Exists
What it adds · The names
Q
no
does what the method does, then returns the object, so the call can be chained
QQ
no
chains on the next, more specific type of object (the Q ladder)
QQQ
no
chains on the most specific type of object (the Q ladder)
QRT
no
returns the result as an object of the requested type
CS
no
takes a case-sensitivity flag
ST
no
takes the position to start from (StartingAt)
IB
no
takes bounds that are included (IncludingBounds)
XT
yes
the extended form: more parameters than the base method · ExtendToPositionXT
XTT
no
yet another extension: a further extended form, after XT
Z
no
includes the position in what it returns
ZZ
no
returns positions as sections, [start, end]
W
no
selects by a condition
WF
no
selects by a condition, with the expressive keywords (@NextItem, @PreviousItem...)
D
no
takes a direction, forward or backward (Directional)
F
no
takes a function (the condition or the update is given as a function); the forms document also uses F for the future form, which defers the action
Many
no
works on a collection of items instead of one (the plural form)
Except
no
takes exceptions, what to leave out (the exceptional form)
U
no
returns the result without duplication
