debugCurvesOn = \layout {
\context {
\Score
\override Slur #'stencil = #(display-control-points)
\override PhrasingSlur #'stencil = #(display-control-points)
\override Tie #'stencil = #(display-control-points) }
}
That created a layout definition (more accurately: an output definition
suitable for use in layouts). Which can be used in \layout:
\layout { \debugCurvesOn [Other stuff ...] }
If you want to turn this into a function, you use define-scheme-function
and construct the return value using #{ \layout { ... } #}.

Not clear to me what you want.
