This should be clearer:
The key type can be string, number, bool or float. Other types result in an
error. Without using [] the value is used as a string, keeping leading zeros.
An expression given with [] is evaluated and then converted to a string.
Leading zeros will then be dropped: >
var dict = {000123: 'without', [000456]: 'with'}
echo dict
{'456': 'with', '000123': 'without'}
