<pre>[class.ctor]p5:
"A defaulted default constructor for class X is defined as deleted if [...] any
non-variant non-static data member of const-qualified type (or array thereof)
with no brace-or-equal-initializer does not have a user-provided default
constructor"
... as clang explains in its diagnostic (which you truncated):
W get() { return W(); } // Line 19
^
<stdin>:4:2: note: explicitly defaulted function was implicitly deleted here
wrap() = default;
^
<stdin>:8:4: note: default constructor of 'wrap<const S>' is implicitly deleted
because field 't' of const-qualified type 'const S' would not be initialized
T t;
