Is changing a

public fun

to

public inline fun

binary and source compatible?

Yes it should be. The inverse however (inline -> not inline) is not source compatible.

Thank you, that's what I thought, but wanted to confirm!

Note also that changing

inline

to

inline

+

reified

is not binary compatible

Why isn't the reverse source compatible?

Because an inline fun can do things a non-inline fun can't e.g. contain suspending functions if the call-site is suspending

Forgot about those 😏.
