## Generic Property Container
# There are several, differing instances where the language accepts
# specific contained keys or contained key, value pairings.
#
# Property Maps:
# - Starts with either `[` or `{`
# - Key separated by `:` or `=`
# - Deliminated by `,`
#
# Property Lists:
# - Starts with `[`
# - Deliminated by `,`
#
# For simplicity, these patterns match a generic, nestable structure
# which follow a key, value pattern. For normal lists, there's only keys.
# This allow some "illegal" structures, but we'll accept those for
# sake of simplicity
#
# Examples:
# - `[facing=up, powered=true]` (blockstate)
# - `[name="hello world", nbt={key: 1b}]` (selector + nbt)
# - `[{"text": "value"}, "literal"]` (json)
