criticism programming unless someone sources this section i'm going to remove it several statements read as or or personal opinion and zero sources exist for example the statement that the c plugin interface for source is bulky insecure or lacks access to core systems without any explanation or source as to why the fact that some mods have chosen to implement lua does not inherently show criticism the one source that existed was for l d gaining squirrel support which didn't support the section's position as a criticism and was moved into the notable upgrades section
