# it gets cleared. This is meant to avoid memory leaks when a rogue prompt is filling the cache
# with data.

# Note: Several performance-critical functions return results to the caller via global
# variabls rather than stdout. This is faster.

# Caching allows storing array-to-array associations. It should be used like this:
#
#   if ! _p9k_cache_get "$key1" "$key2"; then
#     # Compute val1 and val2 and then store them in the cache.

#
# Limitations:
#
#   * Calling _p9k_cache_set without arguments clears the cache entry. Subsequent calls to
#     _p9k_cache_get for the same key will return an error.
#   * There must be no intervening _p9k_cache_get calls between the associated _p9k_cache_get
#     and _p9k_cache_set.
