Mmm, that's a lot of typing to stop it doing something you could
argue it shouldn't do anyway. Oh, and "echo not_a_function()" seems
to currently upset cfengine, causing it to complain that
not_a_function isn't a builtin function. Even when I replace () with
$(leftparen)$(rightparen), appropriately defined.
Multiple interpolation works like this:
control:
foo = ( '$(bar)' ) # Not interpolated
bar = ( "Baz" )
alerts:
geese:: "There is a goose called '$(foo)' in the building." \
with default with default
The last line tells it to interpolate using the variables in the
default namespace twice. First interpolation turns $(foo) into the
literal $(bar). Second one works on the newly-created string and
turns $(bar) into 3.
It's a big culture shock to change a language from implicit
interpolation to explicit, however.
