No, that is not possible. Typechecking in general is really bad on function modules. Just take this snippet for example:

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
 EXPORTING
   input         = lw_string
   test          = someother
   banana_banana = someother
 IMPORTING
   output        = lw_string.

It will trigger a runtime error, but doesn't stop the compilation. Theres only a critical note inside extended program check.

Anyway, inline declarations work on method calls. Most of the old function module code is already translated into OOP.
