A person who does not use paredit can easily create a source file that
does not have matching parentheses. Loading a broken file currently
produces an error like this:
--8<---------------cut here---------------start------------->8---
$ guile -e '(hello'
ERROR: In procedure read:
ERROR: In procedure scm_i_lreadparen: #<unknown port>:1:7: end of file
--8<---------------cut here---------------end--------------->8---
For new users it is not obvious that this error message means that a
closing parenthesis is missing.
Can the message be improved?

In Guix I worked around this with:
https://git.savannah.gnu.org/cgit/guix.git/commit/?id=a6e22d84450450cacc6fc36445f6ae378a5b7ad0
A bit of a hack, but it looks better:
configuration.scm:135:1: missing closing parenthesis
In Guile proper, we could replace “end of file” with “missing closing
parenthesis”, which would already be an improvement, though we’d still
see that “scm_i_lreadparen” and maybe “ice-9” here and there.
