Hi, I was define some functions like `read-file-into-string' and `write-string-into-file' but for various vectors.

That's all functions:

read-file-into-vector read-file-into-byte-vector read-file-into-{u|s}{8|16|32|64}-vector write-vector-into-file write-byte-vector-into-file write-{u|s}{8|16|32|64}-vector-into-file

Like in Scheme's SRFI.
