## (Operators) infix xx

Defined as:

multi sub infix:<xx>()multi sub infix:<xx>(Mu \x)multi sub infix:<xx>(, Num() )multi sub infix:<xx>(, Whatever)multi sub infix:<xx>(, Bool )multi sub infix:<xx>(, Int )multi sub infix:<xx>(Mu \x, Num() )multi sub infix:<xx>(Mu \x, Whatever)multi sub infix:<xx>(Mu \x, Bool )multi sub infix:<xx>(Mu \x, Int )

In general, it returns a Sequence of `$a`

repeated and evaluated `$b`

times (`$b`

is coerced to Int). If `$b <= 0 `

, the empty list is returned. It will return an error with no operand, and return the operand itself with a single operand. An exception `X::Numeric::CannotConvert`

will be thrown if `$b`

is `-Inf`

or `NaN`

.

The left-hand side is evaluated for each repetition, so

say [1, 2] xx 5;# OUTPUT: «([1 2] [1 2] [1 2] [1 2] [1 2])»

returns five distinct arrays (but with the same content each time), and

rand xx 3

returns three pseudo random numbers that are determined independently.

The right-hand side can be `*`

, in which case a lazy, infinite list is returned. If it's a `Bool`

, a `Seq`

with a single element is returned if it's `True`

.
