[RPL/2] Please explain this behaviour

[Adrian Blake]

RPL/2> clear
RPL/2> { 2 3 + } list-> drop eval

1: 5
RPL/2>

as expected, good

RPL/2> { 3 4 * } list-> drop eval

3: 5
2: { 3
      4
      * }
1: 12
RPL/2>

also as expected, good

RPL/2> clear
RPL/2> { 2 3 { 3 4 * } + + } list-> drop eval
+++Error : Invalid argument type for << { 2 3 { 3 4 * } + + } list-> drop eval >> command

3: 2
2: 3
1: +
RPL/2>

result should be 17

or should it be this
{ 2 3 { 3 4 * } list-> drop eval + + } list-> drop eval

no ..fails

So what is the correct syntax?
