Sorry. I get frustrated when people respond only to my message, without
reading the long thread it's in. I'll be more polite in the future.

Hmm, maybe. But then I wondered what if we need to give arguments to the
parser or formatter, and don't want to give them on every parse/format
call. Which means that they should be object, not class methods, and the
constructor would receive those "permanent" arguments.

Sure, but maybe useful in the above case.
Ok, how about this then:
my $format = DateTime::Formats::MySQL->new( ... );
my $dt = $format->parse_datetime( $mysql_dt );
$format->as_timestamp( $dt, length => 8 );
# although I dislike mixing position and named params so maybe ...
$format->as_timestamp( datetime => $dt, length => 8 );
