# NOTE: the behavior of this load method differs a bit from the upstream public
# API, where a file extension may be the preferred method of determining
# the config syntax, even if you specify a Syntax value on ConfigParseOptions.
# Here we prefer the syntax (optionally) specified by the user no matter what
# the file extension is, and if they don't specify one and the file extension
# is unrecognized, we raise an error.
def self.load(file, opts = nil)
# doing these requires lazily, because otherwise, classes that need to
# `require_relative 'hocon'` to get the module into scope will end up recursing
# through this require and probably ending up with circular dependencies.
