expressions that are simple enough to get passed to the "frame var" underpinnings. The parser code will
have to be changed to also query for the dynamic types & offsets as it is looking up variables.
The behavior of "frame var" is controlled in two ways. You can pass "-d {true/false} to the frame var
command to get the dynamic or static value of the variables you are printing.
There's also a general setting:
target.prefer-dynamic-value (boolean) = 'true'
which is consulted if you call "frame var" without supplying a value for the -d option.
