[Verse 1]
In the quantum realm where algorithms hide
Pattern matching builds a fortress wide
By Case syntax splits the data stream
Each condition guards what patterns mean
When the input flows through structured gates
Every branch decides what code creates
[Chorus]
By Case, trace the quantum space
Pattern match, no data lacks
Branch by branch, the logic dance
Quantum threats meet their match
By Case, embrace the syntax chase
Every pattern finds its place
[Verse 2]
Destructuring pulls the values free
Like a surgeon's blade, precision key
Guard expressions filter what gets through
Boolean sentries checking if it's true
Exhaustive matching catches every thread
No quantum surprise leaves logic dead
[Chorus]
By Case, trace the quantum space
Pattern match, no data lacks
Branch by branch, the logic dance
Quantum threats meet their match
By Case, embrace the syntax chase
Every pattern finds its place
[Bridge]
Wildcard patterns sweep the rest
Underscore marks the final test
When all cases can't be named
Let the catch-all be your friend
Compile-time warnings sound the bell
If your patterns don't match well
[Verse 3]
Nested structures peel like quantum layers
Pattern variables become the players
Bind the values as the match succeeds
Extract the data that your function needs
From simple literals to complex forms
By Case handles algorithmic storms
[Chorus]
By Case, trace the quantum space
Pattern match, no data lacks
Branch by branch, the logic dance
Quantum threats meet their match
By Case, embrace the syntax chase
Every pattern finds its place
[Outro]
In the lexicon of quantum code
Pattern matching lights the road
By Case stands as guardian strong
Where quantum logic can't go wrong
