A single-argument constructor without explicit allows an int to convert implicitly to CompressionOptions, so an accidental Compress(reader, writer, 2) compiles without complaint. Nothing in the library relies on the conversion.

A single-argument constructor without explicit lets an int convert implicitly to CompressionOptions, so an accidental Compress(reader, writer, 2) compiles silently. Nothing in the library relies on the conversion, and the style guide asks for explicit on single-argument constructors. Firefox has carried this as a local patch since 1.2.0.
