| <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 |

| <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. |
