slightly offtopic, but have you condsidered cleaning up your regexp list as such: 
my %REGEX = (
    header    = qr/^(?!START:|END:)([^*: ][^:]+):(.+)\n/,
    starttime = qr/^START:\s*(.+)\n/,
    endtime   = qr/^END:\s*(.+)\n/,
    lineitem  = qr/^(?:\* |  )([^:]+):(\d+):(.+)\n/,
);

then you call it as: $REGEX{'header'}

functionally its identical, but when editing code later on, i find it way easier to see whats going on
