What speed advantage comes from a private handler?

[Phil Davis]

Actually here's another situation where I've used 'dispatch' simply to 
avoid a 'do'. But I could as easily use 'send' to get the job done:


function app_helperAppPath pAppName
     dispatch function ( "_helperAppPath_" & the platform ) to me with 
pAppName
     return the result
end app_helperAppPath


function _helperAppPath_MacOS pAppName
     -- Mac-specific app path discovery code
end _helperAppPath_MacOS


function _helperAppPath_Win32 pAppName
     -- Windows-specific app path discovery code
end _helperAppPath_Win32
