⛏️ should imho be called block_info.

IMHO, it would be better to rename block_infot to blockt. This is on the basis that you wouldn't bother creating instances of a struct that didn't contain information. Therefore the word info is redundant in the context of the name. It doesn't really convey any useful meaning to the reader.

const goto_programt::instructiont &instruction)
{
const irep_idt &line = instruction.source_location.get_line();
if(!line.empty())
{
block.lines.insert(unsafe_string2unsigned(id2string(line)));
block.source_lines.insert(instruction.source_location);
}
const auto &add_location = [&](const source_locationt &location) {
const irep_idt &line = location.get_line();
if(!line.empty())
{
block.lines.insert(unsafe_string2unsigned(id2string(line)));

❓ block_infot::lines is a set I presume?

Yes.

block.source_lines.insert(location);
}
};
add_location(instruction.source_location);
instruction.code.visit_pre(
[&](const exprt &expr) { add_location(expr.source_location()); });
}
