Of course I can put the exception handling code into a function 
to not duplicate it. However, I still need to write this 
construct over and over again. Is there a way to handle it more 
generic? Like:

??? (... code ...);

or

??? { ... code ...};

Where ??? would do the try and re-use the exception handling 
code everytime? I hope this is understandable.

Have you looked at std.exception.ifThrown? You could define a 
handler function and pass it to ifThrown for each expression that 
may throw. If it's a statement, I believe you could wrap it in a 
lambda which is immediately called, then append 
.ifThrown(handler).
