Great! Two little pieces of envy/efficiency: 
1.) at least one space token in the macro definition can be avoided; 
2.) \innereolsection needn't be defined anew at each call of \eolsection, cf.:

\def\toeol{% save space token
  \begingroup\catcode`\^^M\active\dotoeol}
{\uccode`\~=`\^^M
 \uppercase{\gdef\dotoeol#1~}{\endgroup\message{^^J#1^^J}}}

[TESTED with a single occurrence and line]

Cf. Wikipedia: "Envy, jealousy and schadenfreude"!

-- I realize: my version can be fooled by redefining \dotoeol, Phil's is more robust in this respect.

Cheers,
