- fix line numbers - forgot to update state.line during execution
- add a comment convention {{/* comment */}}
- set.Template returns the named template in the set
- set.Execute executes the named template in the set
- use a local methodByName so this package can be used with earlier release of reflect.
- use initial cap to detect exported names

This implementation allows a goroutine to do successive acquisitions
of a mutex even if there are blocked goroutines.
Moreover, it allows a newcomer goroutine to acquire a mutex ahead of
blocked goroutines (that is, it does not enforce FIFO).
On implementation level it's achieved by separating waiter count and
locked flag.
