# NOTE: This file was generated from presto.csv, with the following manual modifications:
#
# - Ordering: the ordering of overloads is *significant*! Overload resolution
#   tries candidates in the order they are specified in this file, so more
#   specific signatures must come before more general ones.
# - Incorrect signatures: some functions signatures with variadic arguments are
#   incorrect in presto.csv, and have been corrected here.
# - Duplicate signatures: some functions signatures appear multiple times in
#   presto.csv, and have been deduplicated here.
# - Missing signatures: some functions signatures (e.g. `coalesce`) are
#   straightup missing from presto.csv, and have been added here.
