\textbf in hline text specification doesn't work

[yatescr]

Why doesn't this work?

\begin{tblr}{
colspec={lll},
vlines,
vline{2}={text={\textbf{=}}},
}
0 & pi & 3.14 \
1 & pi & 3.14 \
2 & pi & 3.14 \
\end{tblr}

It is an expansion bug. You can add a \noexpand.

\documentclass{article}
\usepackage{tabularray}
\begin{document}
\begin{tblr}{
colspec={lll},
vlines,
vline{2}={text={\noexpand\textbf{=}}},
}
0 & pi & 3.14 \\
1 & pi & 3.14 \\
2 & pi & 3.14 \\
\end{tblr}
\end{document}

PS: you will know how to enclose latex code in questions in #120.
