I've noticed that Gauche seems to start faster, and that is interesting for scripting, and the documentation is structured better.
first-class regexps ('Scheme regular expressions', or SRE)
what makes it first class? Guile supports regular expression too (https://www.gnu.org/software/guile/manual/html_node/Regular-Expressions.html), and from a first glance, all I see that Gauche has are reader extensions.
I'm considering rewriting a few scripts in Scheme, and in general, it's a pity that Scheme despite all the SRFI's isn't portable enough for real-word development.
