The -display- thing probably comes down to the fact that an expression fed
to it is automatically evaluated... So the whole issue does not strike me as
inconsistent. 

Let`s all hope that "Martine" is a unisex name in your region of the
world...

It looks like one of those things whether a local macro needs to be
evaluated or 
not. For example, all of these work fine.
 
di r(se)
di `r(se)'

di e(rho)
di `e(rho)'
 
But this is inconsistent in a consistent way. Strictly speaking they should
not 
yield the same result, since e(rho) is different from `e(rho)', but being
able 
to evaluate e-class locals would make it consistent with regular locals. As
most 
of us are aware, sometimes one or the other will not work for some usage
(such as
loops, etc) under some versions of Stata.
 
Apparently there is something in outreg2 that will let it handle either
versions 
of e-class locals (with or without being evaluated) but not for r-class
locals. 
This is a little inconsistent, and probably should be fixed. In the meantime

the workaround suggested by Martine should work fine.
