6.3.3. Safe imports — Glasgow Haskell Compiler 9.0.2 User's Guide

# 6.3.3. Safe imports

`Safe`

  Since: | 7.2.1

  Declare the Safe Haskell state of the current module.

`Trustworthy`

  Since: | 7.2.1

  Declare the Safe Haskell state of the current module.

`Unsafe`

  Since: | 7.4.1

  Declare the Safe Haskell state of the current module.

With the `Safe`, `Trustworthy` and `Unsafe` language flags, GHC extends the import declaration syntax to take an optional `safe` keyword after the `import` keyword. This feature is part of the Safe Haskell GHC extension. For example:

    import safe qualified Network.Socket as NS

would import the module `Network.Socket` with compilation only succeeding if `Network.Socket` can be safely imported. For a description of when a import is considered safe see Safe Haskell.
