Usage

Run a block of code in a traditional try block, with options to chain catch and finally handlers as well.

Any errors are passed directly as a single variable to the catch block.

Example of use:

local try = require "try-catch-finally"

local object

try(function ()
    object = Object()
    object:doRiskyStuff()
end)
.catch(function (ex)
    print(ex)
end)
.finally(function ()
    if object then
        object:dispose()
    end
end)
