yes, i use vim and vi text editors for lisp paren matching is essential

it's not like i'm advocating writing code using cli or sed

Writing Lisp without an even more IDE-like feature, macro-expansion, would be almost as painful.

i'm pointing to something deeper, because of high level abstractions, FP codes tend to be short -> can fit in one head; thus, IDE is less essential

no amount of popularity can change that

It's the other way 'round. IDEs appeared because languages like Java require so much scaffolding. Why should I even have to see generated code, let alone write it, that's the compiler's job! Automation (which the exception of simple stuff like paran matching) doesn't add much to succinct languages because there isn't much in your code that isn't directly addressing the problem you want to solve, and that has to come from inside your own head.
