you almost had it. remember, by default velocity does not parse things in
single quotes, but does parse those in double quotes. so as long as your arg1
does not require parsing, you can do:
#set( $foo = "#mymacro( 'arg1' )" )
and the string 'arg1' will be passed to the macro which is then evaluated and
set as $foo.
if you do need arg1 to be parsed, you will either have to use the
(View)RenderTool or else do it in two steps:
#set( $arg1 = "arg1" )
#set( $foo = "mymacro( $arg1 )" )
