Pushes the contents of an Operand onto the front of a Literal (quoted).

Input: {A} {B}

Output: {AB}

Implementation: Om::Language::Operation::LiteralFrontPushOperation

Normalization to a Literal only happens if an append occurs (i.e. the first Operand is non-empty); otherwise, it is left unchanged. However, since everything represents as a Literal, this doesn't make an observable difference.
