The key idea is that the {#1} should be syntactically correct at all times. The
only red underlining we should see in Visual Studio Code should appear under
the placeholders. In general, a good principle for {#2} development is to
start with a {#3} that compiles, perform the smallest change possible to
obtain a new compiling {#3}, and repeat until the {#3} is complete.%
