Oh, sorry! The article is outdated in this regard.
The Vip REPL now no longer behaves this way (triggering evaluation with an
opening parenthesis). Instead, it needs ": " (a colon and a space).
Practically, you get the colon by pressing ':' (as in Vim) or <space>. At this
point you can enter commands like "e" (edit), "w" (write) and so on (see the
full list in the 'command' function in the 'case C' body. BUT if you press
a(nother) space here, the rest of the line will be evaluated.
This is easier than it sounds ;)
Try this: Hit '-' a few times to get a bigger command window. Then hit space,
space,(+ 3 4 and <enter>. The command window shows
: (+ 3 4)
-> 7
The focus is back to the current edit window.
Or, you move to the command window permanently with "qj" or "^wj", and edit
expressions manually. You can (re)evaluate any line there by pressing <enter> on
it.

Not a region (in the sense of as part of a file), but you can evaluate ('load')
the whole file by pressing F7.
Or you copy some lines to the command window ('y' and 'p' commands) and evaluate
them there.
