+The pagespec regexes don't allow functions with no arguments.
+
+IkiWiki.pm, around line 1035:
+
+<pre>
+$spec=~m{
+ \s* # ignore whitespace
+ ( # 1: match a single word
+ \! # !
+ |
+ \( # (
+ |
+ \) # )
+ |
+ \w+\([^\)]+\) # command(params)
+ |
+ [^\s()]+ # any other text
+ )
+ \s* # ignore whitespace
+ }igx
+</pre>
+
+command(params) of course might be just command(). (See
+conditional.pm: match_included.) Trying to feed
+ikiwiki a pagespec without params will get you instead:
+
+IkiWiki::PageSpec::match_glob($page, q{function}, @params) ( )
+
+Which is completely not desired. The second + on that line should be a *.
+
+None of the builtin pagespecs "work" with no parameters, so it's hard to
+write a unit test for this. But can we at least write a helpful note in
+case the user is given to rebuilding the wiki by hand. --Ethan
