Comment(by simonpj):
Johan, if `$weta` was inlined would you be happy?
It's not being inlined just because GHC thinks it's too big (ie static
code size; there's no work-duplication issue here). You can experiment by
increasing the inlining threshold `-funfolding-use-threshold=N`. The
default is 6; try increasing it to 15 or so.
Perhaps primops applications should count as practically free for inlining
purposes?
