panic nameModule tpl_B1{v}
using the attached code, we get
*Main> cfd True
"cfd"
*Main> ctf True
<interactive>:1:0:
No instance for (CTF Bool how)
arising from a use of `ctf' at <interactive>:1:0-7
Possible fix: add an instance declaration for (CTF Bool how)
In the expression: ctf True
In the definition of `it': it = ctf True
but if we uncomment the CTF
instance, we get panic, even for cfd..
*Main> cfd True
: panic! (the 'impossible' happened)
