This sounds like it could be a more surprising be

Yes -- and it's also similar to a few other comment behaviors, like m4's
`dnl`. But it sounds like it would be good to qualify the "similar to
% in tex" comment in the do

Doesn't it already?
#lang at-exp racket
'@stuff{
Hello@; John
World
}
'(stuff "HelloWorld")
See a
Yes, in that case. I meant more the following:
#lang at-exp racket
'@stuff{
Hello@; John
World
}
which currently produces '(stuff "Hello" "\n" " " "World").

swallow everything up to the first non-whitespace character after the

change scribble/decode at all, just the @-reader. Effectively, the only

Having a line comment swallow a newline is helpful when you want to
break up something in the source without a break in the output, as in
Hello@;
World
=>
"HelloWorld"
I imagine that Eli adopted that feature of @-expressions from TeX.

Scribble can't be changed to match LaTeX without changing @-expression
reader at a fairly fundamental way, and I'm skeptical of the change.
Scribble's input is handled in three steps: @-expression parsing to
produce a syntax object (i.e., enriched S-expression), Racket expansion
and evaluation of
Scribble and LaTeX disagree on these documents. Should Scribble be changed
to match LaTeX?
Scribble:
#lang scribble/manual
Hello @; John
World
Output is:
"Hello World"
;; ---
LaTeX
\documentclass{article}
\begin{document}
Hello % John
World
\end{document}
Output is:
"Hello
World"
