oops, PrintFmt is really great. It provides all flexibility to
customization.
For my style of page, I don't like the "sandwiching" of many variables. So
I created one PHP file which does the entire layout. This PHP file has
several
PrintFmt  calls, most of them with a list to support fallbacks.

Unless there is a serious performance drawback, i will stick with PrintFmt.

I do

<?php PrintFmt($pagename, "file:\$Group.menu.php $Group.menu.\$lang.php
default.menu.php somefile.php"); ?>

this is a great feature.

for me it is not easier. The Page Layout variables support "file",
"function" "wiki".

By providing the searchlist, PrintFmt is rally great. And it is even better
to maintain and to change.

I even would like to substitute

     PrintText($pagename, "[[PmWiki:PmWiki [[\$Version]]]]")

by

     PrintFmt($pagename, "text:[[PmWiki:PmWiki [[\$Version]]]]")

By the way: shouldn't

    FmtPageName("\$action", $pagename)

be also swapped to

FmtPageName($pagename, "\$action");

    to be the similar to PrintFmt as you did with StartHTML.

Could we make a function like

LookupFmt("wiki:Main.Homepage your.page his.page")
LookupFmt("file:local/foo/bar foo/bar")

which returns the first alternative found?
