I am trying to implement a simple map function. I found code to
do this in another post but it only seems to work with lambda
functions and I do not understand why. Any help would be greatly

This has nothing to do with which exceptions types a function
throws. The compiler doesn't dig into that. You have to catch
`Exception`.

Greetings everyone,
I have a question regarding the use of [relative
links](https://dlang.org/spec/ddoc.html#reference_links) in DDoc.
According to the specification, you can include a reference to an
object that is in scope using square brackets, e.g. `[Object]`.

if nothrow fails that's because things are checked.

D does not have checked exceptions like Java, so the compiler
doesn't have anyway to verify that any

I'm not sure what you mean. If a function throws an exception, it
can't be nothrow.

What map and other Phobos algorithms return are called Voldemort types
for the reason you state: They are unmentionable. The usual way is to
return 'auto'

Oh, that’s an unfortunate limitation but at least there’s a
workaround.
following this example in the documentation of map:
```

alias stringize = map!(to!string);
