Make panics more useful by printing values, if their
underlying kind is printable, instead of just their memory address.
Thus now given any custom type derived from any of:
float*, int*, string, uint*
if we have panic with such a result, its value will be printed.
Thus given any of:
type MyComplex128 complex128
type MyFloat64 float64
type MyString string
type MyUintptr uintptr
panic(MyComplex128(32.1 + 10i))
panic(MyFloat64(-93.7))
panic(MyString("This one"))
panic(MyUintptr(93))
They will now print in the panic:
panic: main.MyComplex64(+1.100000e-001+3.000000e+000i)
panic: main.MyFloat64(-9.370000e+001)
panic: main.MyString("This one")
panic: main.MyUintptr(93)
instead of:
panic: (main.MyComplex128) (0xe0100,0x138cc0)
panic: (main.MyFloat64) (0xe0100,0x138068)
panic: (main.MyString) (0x48aa00,0x4c0840)
panic: (main.MyUintptr) (0xe0100,0x137e58)
and anything else will be printed as in the past with:
panic: (main.MyStruct) (0xe4ee0,0x40a0e0)
Also while here, updated the Go1.15 release notes.
Fixes #37531
