[Q] extracting value from a structure ... [message #12793]

Consider the following:

r = {name: 'john', age=18}
s = 'age'

Given the string s, is there an easy way to
extract the value of the corresponding tag
in r? s is not known at compile time so
the trivial r.age reference is not possible.
My current solution is:

command = 'v=r.'+s
execute(command)
print, 'age=',v

but this is slow because of the run time
compilation of 'command'. Surely there
is an easier way ...

Cheers,
Darran.
