However, I don't like the idea of typing the word twice (lowercase, then
uppercase),
The doc string for `replace-regexp` has this:
```
In interactive calls, the replacement text may contain ‘\,’
followed by a Lisp expression used as part of the replacement
text. Inside of that expression, ‘\&’ is a string denoting the
whole match, ‘\N’ a partial match, ‘\#&’ and ‘\#N’ the respective
numeric values from ‘string-to-number’, and ‘\#’ itself for
‘replace-count’, the number of replacements occurred so far, starting
from zero.
```
So what you can do is:
M-x replace-regexp RET
parser RET
\,(upcase \&) RET
Place point at the start of the buffer (or wherever you want to start the
replacement), since the command works from point.
