This is a dupe of 3797, the purity of a function pointer (among other things)
is not checked when performing implicit conversions.

With dmd pull 88 you get the following error from dmd:
testx.d(26): Error: constructor testx.S.this (int function(int) pure func) is
no
t callable using argument types (int function(int num))
testx.d(26): Error: cannot implicitly convert expression (& add1) of type int
fu
nction(int num) to int function(int) pure
