Local vars would be very nice to have in configs.

<verbatim>
[myvars]
abcd 1234

[configf:settings line-end-comments yes]
[configf:settings use-section myvars]

[somesection]
VAR1 #{abcd}                       # VAR1 will get 1234 for a value
VAR2 #{VAR1}                      # by default a #{...} with no spaces will look up the var in the current section and then the use-section section.
</verbatim>
