#
# There, a colon would be skipped but not a dollar.
# Parsing therefore continues at the '$' of the ${:U159...}, looking
# for an ordinary variable modifier.
#
# At this point, the ${:U} is expanded and interpreted as a variable
# modifier, which results in the error message "Unknown modifier '1'".
#
# If ApplyModifier_Gmtime were to pass its argument through
# ParseModifierPart, this would work.
