Out is a helper function to call functions which returns (error) and start error handling with DSL.

Out1 is a helper function to call functions which returns (T, error).

Out2 is a helper function to call functions which returns (T, error).

T is similar as [To] but it let's you to annotate a possible error at place.

T1 is similar as [To1] but it let's you to annotate a possible error at place.

T2 is similar as [To2] but it let's you to annotate a possible error at place.

T3 is similar as [To3] but it let's you to annotate a possible error at place.

To is a helper function to call functions which returns an error value and check the value.

To1 is a helper function to call functions which returns values (T, error) and check the error value.

To2 is a helper function to call functions which returns values (T, U, error) and check the error value.

To3 is a helper function to call functions which returns values (T, U, V, error) and check the error value.
