Not sure I follow your question, however to emulate a stack you can use the shift and unshift operations (perldoc -f shift to see how it is used)

XkbKeySymEntry(3)						   XKB FUNCTIONS						 XkbKeySymEntry(3)

NAME
XkbKeySymEntry - Returns the keysym corresponding to shift level shift and group grp from the two-dimensional array of keysyms for the key corresponding to keycode SYNOPSIS
KeySym XkbKeySymEntry macro ( xkb, keycode, shift, grp ) XkbDescPtr xkb; KeyCode keycode; int shift; int grp; ARGUMENTS
- xkb Xkb description of interest - keycode keycode of interest - shift shift level of interest - grp group of interest DESCRIPTION
The key width and number of groups associated with a key are used to form a small two-dimensional array of KeySyms for a key. This array may be different sizes for different keys. The array for a single key is stored as a linear list, in row-major order. The arrays for all of the keys are stored in the syms field of the client map. There is one row for each group associated with a key and one column for each level. The index corresponding to a given group and shift level is computed as: idx = group_index * key_width + shift_level The offset field of the key_sym_map entry for a key is used to access the beginning of the array. XkbKeySymEntry returns the keysym corresponding to shift level shift and group grp from the two-dimensional array of keysyms for the key corresponding to keycode. X Version 11 libX11 1.2.1 XkbKeySymEntry(3)
