Question
Daniel, In function parse_expressionable_single, why we need NODE_FLAG_INSIDE_EXPRESSION flag? Flags start with NODE_FLAG_ are for nodes, not for history, I can't understand.
int parse_expressionable_single(struct history *history)
{
struct token* token = token_peek_next();
if(!token)
return -1;
history->flags |= NODE_FLAG_INSIDE_EXPRESSION; //Why we need this?
