Choosing a Language Based on its Syntax?

AI-Generated Deep Dive Summary
Choosing a programming language based solely on its syntax can be misleading, as semantics often play a far more critical role in determining a language’s value. The article challenges the notion that declaration syntax is the defining feature of a language, arguing that even significant changes to syntax—such as type-focused, name-focused, or qualifier-focused declarations—do not fundamentally alter the underlying semantics. For experienced programmers who understand how compilers process these declarations, the choice of syntax becomes largely a matter of personal preference or ergonomics rather than a determinant of functionality.
The article highlights that denotational semantics, which define what code means rather than how it is executed, are far more important when evaluating a language. This perspective shifts the focus from superficial aspects like syntax to the actual meaning and behavior of the language. For instance, altering declaration syntax in a language like Odin may require minor adjustments to the compiler but does not significantly impact its core functionality or the way it processes semantics.
One example of this is the debate over semicolons in programming languages. While some modern languages have moved away from semicolons as statement terminators, many still use them due to their foundational role in parsing and error handling. The article suggests that dislike for semicolons often stems from a lack of understanding about their purpose or from personal aesthetic preferences rather than practical concerns.
Ultimately, the article emphasizes that syntax matters only when it directly impacts usability or performance, which is rarely the case. For developers focused on solving problems efficiently, prioritizing semantics over syntax leads to more informed decisions about language adoption. This perspective is particularly valuable for tech enthusiasts and professionals who need to evaluate tools based on their actual capabilities rather than superficial traits
