# builtin::compat(3pm)

Provide builtin functions for older perl versions

## NAME

builtin::compat - Provide builtin functions for older perl versions

## SYNOPSIS

```
  use builtin::compat qw(
    true
    false
    is_bool
    inf
    nan
    weaken
    unweaken
    is_weak
    blessed
    refaddr
    reftype
    created_as_string
    created_as_number
    stringify
    ceil
    floor
    trim
    indexed
    load_module
  );
```

## DESCRIPTION

Provides builtin functions for perl versions that do not include the builtin module.

No functions are exported by default.

This module does its best to behave similar to builtin, which creates its exported functions as lexicals. The functions will be created in the currently compiling scope, not the immediate caller of `"builtin::compat->import"`. The functions will also be removed at the end of the compilation scope using namespace::clean.

The builtin functions will be used directly when they are available.

## FUNCTIONS

- true

  See "true" in builtin.

- false

  See "false" in builtin.

- is\_bool

  See "is\_bool" in builtin.

  Prior to perl 5.36, it was not possible to track boolean values fully accurately. This function will not be perfectly accurate on earlier perl versions.

- inf

  See "inf" in builtin.

- nan

  See "nan" in builtin.

- weaken

  See "weaken" in builtin.

- unweaken

  See "unweaken" in builtin.

- is\_weak

  See "is\_weak" in builtin.

- blessed

  See "blessed" in builtin.

- refaddr

  See "refaddr" in builtin.

- reftype

  See "reftype" in builtin.

- created\_as\_string

  See "created\_as\_string" in builtin.

  Prior to perl 5.36, it was not possible to check if a scalar value was created as a number or as a string fully accurately. This function will not be entirely accurate before then, but should be as accurate as is possible on these perl versions. In particular, a string like "12345" that has been used as a number will cause `"create_as_string"` to return false and `"created_as_number"` to return true.

- created\_as\_number

  See "created\_as\_number" in builtin.

  Has the same caveats as `"created_as_string"`.

- stringify

  See "stringify" in builtin.

- ceil

  See "ceil" in builtin.

- floor

  See "floor" in builtin.

- trim

  See "trim" in builtin.

- indexed

  See "indexed" in builtin.

- load\_module

  See "load\_module" in builtin.
