You want to make sure that when things change, you keep the formatting
in sync. This makes it a bit more tedious, as you need to scan the
code. The above causes "func" to no longer be in line with the rest of
the data structure. Note, this is a common error with changes like
this, especially when they affect a lot of files like this change set
does.
You may want to scan all the code that was changed to make sure that
there's no other modifications of formats caused by name changes.
Thanks!
