An HscEnv is used to compile a single module from plain Haskell source

the module graph don't change during a single compilation.
</p><p>Historical note: "hsc" used to be the name of the compiler binary,
when there was a separate driver and compiler. To compile a single
module, the driver would invoke hsc on the source code... so nowadays
we think of hsc as the layer of the compiler that deals with compiling
a single module.
