would this dispatcher like syntax be OK for you?

till (
  - /match0/ => \&doOtherProcessing,
  - /match1/ => \&doStage1,
  - /match2/ => \&doStage2,
  - /match3/ => \&doStage3,
)

[download]

of course you are also free to write something like

till (
  - /match0/ => sub { print "default Processing" },
  - yadda yadda ...
)

[download]

please note that the minus is obligatory to:

Furthermore you'll need to bind the state¹ of till() to it's position, i.e. using caller to determine filename and line number of invocation.

¹) e.g. the $fn here

²) Consequently you shouldn't use two till()'s within the same line, otherwise they'll share the same state.

³) minus transforms true => -1 , false => 0
