SourceLoc
loc~ : 
type SourceLoc
Represents a source code location in a MoonBit program, containing
information about the file path, line number, and column number. Used
internally by the compiler for error reporting and debugging purposes.
This type is public to all packages but its internal representation is
opaque. Users cannot construct values of this type directly; they are
automatically created by the compiler when needed.

(self : Double, other : Double) -> Double
Performs subtraction between two double-precision floating-point numbers.
Parameters:

self : The first operand (minuend).
other : The second operand (subtrahend).
Returns the difference between the two numbers according to IEEE 754
double-precision arithmetic rules.
Example:
test "Double::op_sub" {
  let a = 5.0
  let b = 3.0
  inspect(a - b, content="2")
  inspect(0.0 / 0.0 - 1.0, content="NaN") // NaN - anything = NaN
}

(self : Double) -> Double
Returns the absolute value of a double-precision floating-point number.
Parameters:

value : The double-precision floating-point number to compute the
absolute value of.
Returns the absolute value of the input number. For any input x, the result
is equivalent to if x < 0.0 { -x } else { x }.
Example:
test "abs" {
  inspect((-2.5).abs(), content="2.5")
  inspect(3.14.abs(), content="3.14")
  inspect(0.0.abs(), content="0")
}

(msg : String, loc~ : SourceLoc) -> Unit!Failure
Raises a Failure error with a given message and source location.
Parameters:

message : A string containing the error message to be included in the
failure.
location : The source code location where the failure occurred.
Automatically provided by the compiler when not specified.
Returns a value of type T wrapped in a Failure error type.
Throws an error of type Failure with a message that includes both the
source location and the provided error message.
Example:
test "panic fail" {
  fail("Something went wrong")
}
fail!("|\{
Double
x} - \{
Double
y}| <= \{
