                <span style="font-family:monospace"><span class="command"><strong>lassign_array</strong></span></span> is an utility command inspired by the same Tclx command and 
                with a close resemblance with Tcl's <span style="font-family:monospace"><span class="command"><strong>lassign</strong></span></span> for assigning list elements to variables.
                <span style="font-family:monospace"><span class="command"><strong>lassign_array</strong></span></span> first argument is a list of values to be assigned to an array that must be 
                given as second argument. The remaining arguments are the array's variable names which will store
                as values the elements of the list. Variables names don't matching values in the list are given an empty string. 
                Unassigned list elements are returned as a list.
