{ok,[{'{',1},
{atom,1,form},
{',',1},
{atom,1,personalinfo},
{',',1},
{'[',2},
etc...
(dcr@REDACTED)28> erl_parse:parse_exprs(B ++ [{dot,1}]).
{ok,[{tuple,1,

{atom,1,personalinfo},
{cons,2,
{tuple,2,[{atom,2,firstname},{atom,2,string}]},
{cons,3,
{tuple,3,[{atom,3,lastname},{atom,3,string}]},
{cons,4,{tuple,4,[{atom,4|...},{atom|...}]},
{nil,5}}}},
{'fun',6,
{clauses,[{clause,7,
[{var,7,'List'}],
[],
[{call,7,{atom|...},
[...]}]}]}}]}]}
