Imports of package typecheck

PathSynopsis
bufioPackage bufio implements buffered I/O. It wraps an io.Reader or io.Writer object, creating another object (Reader or Writer) that also implements the interface but provides buffering and some help for textual I/O.
bytesPackage bytes implements functions for the manipulation of byte slices.
cmd/compile/internal/base
cmd/compile/internal/ir
cmd/compile/internal/types
cmd/internal/bioPackage bio implements common I/O abstractions used within the Go toolchain.
cmd/internal/goobj
cmd/internal/obj
cmd/internal/src
crypto/md5Package md5 implements the MD5 hash algorithm as defined in RFC 1321.
encoding/binaryPackage binary implements simple translation between numbers and byte sequences and encoding and decoding of varints.
fmtPackage fmt implements formatted I/O with functions analogous to C's printf and scanf.
go/constantPackage constant implements Values representing untyped Go constants and their corresponding operations.
go/tokenPackage token defines constants representing the lexical tokens of the Go programming language and basic operations on tokens (printing, predicates).
ioPackage io provides basic interfaces to I/O primitives.
mathPackage math provides basic constants and mathematical functions.
math/bigPackage big implements arbitrary-precision arithmetic (big numbers).
osPackage os provides a platform-independent interface to operating system functionality.
reflectPackage reflect implements run-time reflection, allowing a program to manipulate objects with arbitrary types.
sortPackage sort provides primitives for sorting slices and user-defined collections.
strconvPackage strconv implements conversions to and from string representations of basic data types.
stringsPackage strings implements simple functions to manipulate UTF-8 encoded strings.
syscallPackage syscall contains an interface to the low-level operating system primitives.
unicodePackage unicode provides data and functions to test some properties of Unicode code points.
unsafePackage unsafe contains operations that step around the type safety of Go programs.
