Function to syntax tree

[bokner]

Hi,

erl_scan and erl_parse can turn function represented by string into
AST. For example,

1> {ok, S, _} = erl_scan:string("fun(X) -> X+1 end."),
1> {ok, P} = erl_parse:parse_exprs(S),
1> [F] = P, erl_syntax:type(F).
fun_expr

My question is: how do I do the same, but  with the function itself
instead string representation? I.e.,

F = fun(X) -> X +1 end,

AST = <some code turning F into AST>,
fun_expr = erl_syntax:type(AST).

Thanks,
Boris
