I tried that, but it didn't work as expected.

When using a single = sign, it does not improve performance, because the 
expression is reevaluated each time the variable is used.

When using the := operator instead, the affectation is made only once, 
but very early. On the first time, the file includepath does not exist 
yet, so the variable remains empty.

This is why I gave up.
Maybe there is another simple solution.
