Thanks Allan :-)

I ended up making something like this : 

real*${1:8}${2: a/d}${2/(,a)|(,d)/(?1:llocatable)(?2:imension)/}
${2/,a|(,d)/(?1:\()/}$5${2/,a|(,d)/(?1:\))/} :: ${3:name}
${2/,d|(,a)/(?1:\()/}$4${2/,d|(,a)/(?1:\))/}
$0

It's not perfect (there are unwanted tab stops) but I still find it
more convenient than putting the caret between the braces
“by hand”.
