Right now, if you define a function in a pxd file but not in the
corresponding pyx file, Cython doesn't complain, and the error you get
(from gcc) looks like
/var/folders/Oh/Oh9hCPW1Grib+lCgJJ4+-k+++TI/-Tmp-//ccovTRcs.s:19785:non-relocatable
subtraction expression,
"___pyx_f_4sage_6groups_8perm_gps_9partn_ref_22canonical_augmentation_augmentation_is_canonical"
minus "L00000000014$pb"
/var/folders/Oh/Oh9hCPW1Grib+lCgJJ4+-k+++TI/-Tmp-//ccovTRcs.s:19785:symbol:
"___pyx_f_4sage_6groups_8perm_gps_9partn_ref_22canonical_augmentation_augmentation_is_canonical"
can't be undefined in a subtraction expression
error: command 'gcc' failed with exit status 1
I'm somewhat prone to make this mistake, and I was wondering if Cython
could complain before going to gcc.
